I think I have already sent you the code concept. Only thing you need to do is giving proper image path for different size of image. Checkout the following articles to display images in gridview. 1. http://www.devasp.net/net/articles/display/692.html 2. http://www.aspxcode.net/free-asp-net-data-sample-source-code.aspx?Topics=How%20to%20display%20images%20in%20GridView

For all the images you can have two images.One is small in size another one is bigger. Now based on selection you can display the small or big image.

hi all Actually i need to display pictures in gridview in thumbnail size . when user clicks on the thumbnail picture  large sized picture should be displayed.Is it possible to do .If yes then how can i do it.

Say u have created the following to hold the image Now in your code behind get the image Path and display it. Something like this. imgEvent2.ImageUrl = dstEvents.Tables[Events].Rows[intIndex][evm_txt_EventImagePath].ToString(); I am using dataset(dstEvents) to fetch the record from table. Make sure the path contains the image correctly.

I think is better to save link of that picture in the SQL and after call the link of that picture.
