Performance - Directory Structure For Storing Images?
Nov 15, 2010
I'm working on an application which will store around 50.000 images within it's first year and another 75.000 in it's second. Images can come from Galleries, news images, article images and profile images. So I want to give each image a GUID and store the GUID in the database.As for the directory structure i was thinking of something like this:
~/Upload/Images/F2/50/F2504E0-4F89-11D3-9A0C-0305E82C3301.jpg
So I'm using the first 4 characters of the GUID as my directory structure to spread images a bit more evenly between directories. Now I have some questions about this approach:Is it considered good practice to store all different kinds of images together rather then use ~/Images/Upload/Profiles, ~/Images/Upload/Articles etc.I'm also storing thumbnails and they have a different GUID obviously so the thumbs will not be in the same folder as the original and somehow that doesnt give me a good feeling but I guess it should not matter but.Same goes for Galleries, I'm used to store galleries in folders like ~/Images/Upload/Galleries/12 , and now all the images from a gallery will be scattered around in different subfolders, is this a big performance hit?Do you guys have any other ideas for directory structures?
As you can probably see I'm a bit afraid to use this approach but since there will be lots of images maybe even more then the numbers i gave i have to let the control go I think :)

This is in my opinion an abstract problem and I hope I can explain it well. I happened to find the same kind of problem in a completely different project and now I have it again and I would like to avoid it if possible.
I'm creating some classes to simplify some tasks for some specific requirements we have in some projects at work.
I have a class that creates objects which maps the values from webcontrols to an object properties similar to this
[URL]
The problem I have it's sometimes I have to store a non container object in a place (in an object's attribute) and sometimes I have to a store a container object in the same place for storing the values of a webcontrol (a webcontrol can sometimes hold several values like a checkboxlist). I dont like this at all, because some time ago when working in a non commercial compiler, when parsing and generating the intermediate code I had sometimes to store a container in a place, and sometimes I had to store a non container in the same place, and having to ask in other parts of the code if what you are reading is this type of object, or this another type of object, it is something really annoying and it mess up the code. Is there any tips about what it would be better to do to avoid this kind of situations or nothing can be done to avoid it sometimes?

I have a large directory structure with JavaScript, images, etc. that depend on each other. I would like to encapsulate it all into a DLL so I only have to reference one thing and not have multiple copies of all these files across projects.
Because the files depend on each other, I'm thinking I can create an IHttpModule that registers a route to accept URLs such as /MyEmbeddedDir/subdir/file.js. Anything in MyEmbeddedDir would then be handled by a custom IHttpHandler that does the correct mapping. Each web application would then need to reference the DLL and add the module and handler to web.config. Does this seem reasonable?Also, is there an easier way to embed/reference the files than to set the build action to embedded resource and add [assembly: WebResource(...)] to each file (there are dozens!)?Edit: If I'm not using WebResource.axd then I shouldn't need to add [assembly: WebResource(...)]

I'm building a site that can possibly have millions of users (yes ambitious!). Each user can upload an image or two for his/her profile. How would you architect the directories to support this type of thing? I was thinking of having a users subfolder off the root dir where each user will have their own sub-dir that corresponds to their userId created at registration time. I could then upload their profile pics to their corresponding sub-directory under the users dir. Seems straightforward but am I missing anything? Can I have a million sub-dirs under the user dir? NTFS supports it so my guess is YES.

currently in our application we have an ApplicationConfiguration class. It is basically just a static class with const values specifying certain application-global configuration options. Some of these values will rarely if ever change and are only put into the configuration for elegance/cleanness.
Some of these values though do need to be different between production and development. So I'm considering making this class just a wrapper over Web.config. These values are checked many times throughout our codebase. If I change these from a const to a read-only getter that reads from Web.config will this affect compiler optimizations or make our application in any way slower?

Can you point me to a url for the proper directory structure to create for a new website?I can create a website project and add class library projects to the solution to create a fully functional website.My grey area is that I need to zip up the web site solution and hand it over to the client.I'd like to make sure that I hand over a solution with the most proper directory structure.I'll run you through a scenario:
1. Select File > New > Web Site > ASP.NET Web Site from the main menu
2. Save with a path of C:ProjectsTestWebSite
3. Right-click the solution in VS and select Add > New Project > Class Library
4. The new class library is added with an automatic path of C:ProjectsTestWebSite (2)MyClassLib1
It seems like there should be a way to create a better structure for this but I'm just not following the correct process. Can you point me to a url with instructions for managing a proper structure for this?

I'm looking much more closely at the idea of universal conventions over configuration for my projects (versus 'home-rolled' conventions, or grabbing from a variety of conventions).However, I'm not seeing much, if anything, about the preferred location of ASHX files in, for example, ASP.NET MVC projects (as well as Web forms projects).
Is there a recommended directory structure for these? Perhaps there's a published specification with a much larger directory structure accounted for?My personal convention has been to place these within a top-level Handlers directory, but I honestly haven't personally seen any other projects that really do this.I suppose, depending upon what it does (for example, generating an image), that one could argue this might go into the Content directory, but it seems this directory is generally used for static files.(Aside: One could argue that ASHX files are not needed in MVC projects, but based on questions posted here, it appears ASHX files still have their place in MVC projects.)EDIT: Ignore MVC projects, since I'm suggesting that as one example. How about Web Forms, then?

I am designing an prototyping an app the needs to store images, similar to facebook. This will be a public facing site and I am not sure how many users I will end up with but what I am looking for is a way to efficiently retrieve them.
So far I am thinking of storing them in SQL Server varbinary columns. I have the upload code and the storage code for that. My concern is retrieving them. I can retireve and build the image tag on the fly but I am worried about having to hit the database for each one.
I have been thinking about getting all images for a user and caching them in the asp.net cache for 10 to 30 seconds. I have never had to do something like this so I would be interested in hearing a few different approaches. Obviously the images can vary in size and I was thinking about defining a size limit, but I haven't gotten that far yet.

I'm building a Web application that will eventually contain a lot of images. These images will need to be displayed in different formats across the site. What would be the pros/cons of the two solutions:
Storing various versions of the picture when they are uploaded (e.g. thumb, small, medium, large, verylarge)
Resizing the image through the URL - e.g. /Content/Image/1?height=300
Edit:I had a really hard time accepting one answer over the other, so for anyone reading this q/a, take your time to read both answers because the accepted answer was selected by the flip of a coin :) They're both equally good.

I suppose this question has been asked to death all over the web, but I can seem to find a clear cut answer. What I am trying to achieve is as follows: I have a web application that lists various products, their descriptions, names etc and also an image of that specific product. The user will type in a product code or name of the product and a page will pop up with al the previous mentioned info and image or images of that specific product. The problem I am having is: I read somewhere that storing images in a database is 'bad idea' since it effects performance, then I read somewhere else to keep it in the images / or app_data folder. But what would be the best approach and how would I call it from the database (if that's the best way)? And if App_Data / images are the way to go how many images can I put in there (??) already the product catalog has several hundred images of various products. So how would one go about sorting everthing in those folders without having a few hundred images rolling down in my solutions explorer.

I would like to know which is better? Storing images in BLOB or in the File System ? I've got around 400 to 5000 images.
And at run time there are chances where I'll need to retirieve about 100 - 150 images.

I am trying to build a small e-commerce website that will allow user to upload and store the image of their product in the database and also the user could upload the image of the product and compare it with all the similar product images that are already stored in the database. I am using MS ASP.Net using VB.Net as the front end.
if MS SQL server is the best option to carry out such task or should I consider some other database to do this in terms of complexity involved as well as the integration with MS .Net framework.

I'm working in ASP.NET 4.0, and I've got a large web form which represents a single business entity. A user can upload multiple images associated with the entity. The entity is created and assigned a GUID upon submitting the form. The files will be stored to a file system.
The problem is that we have to name the files after the GUID that is assigned to the entity after it is inserted to the database. So before the submit button is clicked, we will have several image files floating around in limbo.
There are obvious answers to this question -- you save the images to the file system and then when the business entity is created, you rename those files. However, I believe that there must be very strong patterns and several key details that would make for a very robust system. What's best practice for this scenario?

I am trying to load every image *.png in a folder on my site. I simply want every image to be shown. One after the other, all on one page. Displaying a single image seems simple enough, but going through the entire directory is tough. How could I do this with minimum code using asp.net with vb as the language?
