I recently needed to have thumbnails for some images that we uploaded to SharePoint for display in a thumbnail library. I couldn’t find any documentation on how to get a thumbnail for an image. So I fired up Fiddler opened up the script and figured out what the hundreds of lines of JavaScript was doing behind the scenes.
Basically, you take an append _t to the directory, convert the period in the file name to an underscore and append .JPG. Here are a few examples:
Using a _w instead of a _t seems to give a slightly larger image. This might be useful for hover over events.

Hi,
I wisht to have a list that contains details about an item including a thumbnail of the picture attached to that item.
How can I create thumbnails of attached pictures?
Thanks
Kind regards
Chris
I don’t know that this is possible. The functionality is actually implemented on the picture library. You could investigate adding the fields you want to a picture library and make the item the picture library itself.
