I need a place to store images. My first thought was to use the database, but many seems to recommend using the filesystem. This seems to fit my case, but how do I implement it?
The filenames need to be unique, how to do that. Should I use a guid?
How to retrieve the files, should I go directly to the database using the filename, make a aspx page and passing either filename or primary key as a querystring and then read the file.
What about client side caching, is that enabled when using a page like image.aspx?id=123 ?
How do I delete the files, when the associated record is deleted?
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.
Assumptions: Microsoft stack (ASP.NET; SQL Server).
Some content management systems handle user-generated content (images, file attachments) by storing it in the file system. Others store these items in the back end database.
Some examples of both:
[code]....
What's the best approach, and why? What are the pros and cons of keeping user files in the database? Is there another approach?
Is it better to store images directly in a database or to just store the name of the file in the db and display that file? I would think that just storing the filename of the image would keep the db size low...

View 2 RepliesI am developing an asp.net application using visual web developer 2005. I have a panel in which i have set a background image. when i run the project the image would not display in the panel, instead if i set the backColor property to say red, the panel filled with red color is displayed but not the image. i have tried an image box also, but the problems persists.
i have only started the project, and literally thats the only code i have got so far, no complication code nothing, thats why i hope i dont need to copy any code here, however if any body wants it, i will get u whatever line of codes i have.
I have added the following code to my web.config file:
<system.diagnostics>
<trace autoflush="false" indentsize="4" >
<listeners>
<add name="myListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="d:debugging.txt" />
<remove name="Default"></remove>
</listeners>
</trace>
</system.diagnostics>
And I have written this line for sending trace output:
System.Diagnostics.Trace.Write(sID + " tracing id");
But, I can not see any "debugging.txt" file created on my d: drive and there is no trace output.

I would like to display images from an xml file containing the url of traffic cameras in Tennessee. The xml file is located at: http://ww2.tdot.state.tn.us/tsw/GeoRSS/TDOTCameraGeorss.xmlI can get the images to display in a datagrid, however, I would like to display them all on the same page (not one per row/cell). Here is what I am trying to get it to look like (just a series of img objects):http://www.vanderbilt.edu/vector/traffic/nashvillecams.htmIs there a way to create an image for each row received in the data table? Eventually, I want this to filter based on city...and each city has a different number of cameras, so hardcoding the images in the page isn't an option. I am hoping there is an efficient way to create the images on the fly and bind the url from the xml to each image.Here is some code that works when 3 images are hard-coded:

View 3 RepliesI have created a simple ASP.NET Website in Visual Studio 2010. I have got a Default.aspx page that contains an image. When the image is located in the Images folder it displays perfectly. When I move the image to another folder, or a sub-folder of the Images folder, it still displays in the Designer, but not in Internet Explorer. In IE, it shows nothing. When I view the source in IE the image tag is there, but nothing is displayed. I navigate to the root folder of the site (which I can do on the dev Web server), go into the Images folder, then go to the image - it displays perfectly. But when I navigate to another folder, or a sub-folder in Images, and try to go to the image, it does not display. I opened the page in google chrome, opened the dev tools, and saw that the image was there, but it was 1x1 pixel and 43 bytes, which doesn't make sense because the image is 38KB.
Code of Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
I want to display my image in image control but the criterias are listed below.
1) It's an intranet application
2) Load image from the different server.
3) Image name would be like 123.jpg
4) My image is in "C:ProjectImages123.jpg" and My server name is "MyServer".
My question is how can I display images from the different server? and How do I write ImageUrl if it is different server?
how can I upload or save files from SQL to ASP .NET and viceversa?
