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 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 am a new-bie in Asp.Net.I am working in a project where I need to store an attachment which will be uploaded by the user in radGrid into Sql server 2005 database.After storing this attachment, I have to retrieve this attcahment and show the same to the other users in radGrid so that they will be able to download the attachment and see that.How should I do that?what kind of datatype would it be?
View 2 RepliesI've got a table where i'm storing a CheckBox.Checked value.
I'm using C# and the value of the field in the table im writing to is a bit.
myDS.InsertParameters["p1"].DefaultValue = CheckBox1.Checked.ToString();
The value placed in my table ends up being either "True" or "False".
So when I try to query the table based on that value with a stored procedure it doesn't work since its looking for a 1 or a 0.
I think the .ToString() is part of the problem but i don't know the syntax to have the value from the CheckBox.Checked to be written as 1s or 0s instead of true or false.
I am facing a problem with retrieving an image and showing it on asp.net grid. I migrated MS Access database to sql server. Image are visible in Crystal report when fetched from the same database (migrated sql server database). But same images are not visible in ASP.Net grid view or simple asp.net image control. Following is my code
SqlConnection oConn =
new
SqlConnection(ConfigurationManager.ConnectionStrings["csr"].ToString());
oConn.Open();
SqlCommand oraCmd = oConn.CreateCommand();
oraCmd.CommandText = "select top 1 photo from [test] where photo is not null";
SqlDataReader dr =
null;
dr = oraCmd .ExecuteReader ();
if(dr.Read ())
if (dr["photo"] !=
null)
{
Response.ContentType = "image/gif";
Response.BinaryWrite((byte[])dr["photo"]);
}
This function is getting called from another page . "hlopen" is hyper link in the grid. hlopen.NavigateUrl = "GetPhoto.aspx?id=1";
I want to remove Lable below barcode image as shown in this exmaple:-
[URL]
<script type="text/javascript">
function GridDataaa() {
debugger;
[Code]....
my output

View 4 RepliesI'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 :)
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 used SQL SERVER 2008 R2 express as my web development database and I set its compatibility level to 2005. Unfortunately this database cannot be be attached to SQL server 2005. Are there any other options?
View 3 RepliesI 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.

View 17 RepliesI 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.
