There's a rather large image in a Stack Overflow post that I'd like to replace with its thumbnail and a link to the full-size image.

I know Imgur generates thumbnails for its images when you upload, but since I'm not the original uploader, is there any way for me to find the thumbnail image by URL hackery or some such?

I can't actually find it documented anywhere, but I uploaded an image and played with the "More Sizes" list:



I haven't included the image inline, because StackExchange would automatically scale it down. To view the original at its full size, click the link.

Large thumbnail

http://i.stack.imgur.com/YdJZtl.jpg (added an l after the image ID)

Small square

http://i.stack.imgur.com/YdJZts.jpg (added an s after the image ID)

It doesn't always handle transparency well, but "small square" is probably what you want.

Here's the API documentation - the ones listed above are all the available image sizes: api.imgur.com/resources_anon#image_hash – Ciaran Jun 10 '11 at 7:01
@Ciaran: All the documented ones. There are -h, -m and -b too. – himself Jul 6 '11 at 11:44

There are 6 total thumbnails that an image can be resized to. Each one is accessable by appending a single character suffix to the end of the image ID, and before the file extension.

For example, the image located at http://i.imgur.com/12345.jpg has the Medium Thumbnail located at http://i.imgur.com/12345m.jpg

The thumbnails are:

  • s = Small Square (90x90)
  • b = Big Square (160x160)
  • t = Small Thumbnail (160x160)
  • m = Medium Thumbnail (320x320)
  • l = Large Thumbnail (640x640)
  • h = Huge Thumbnail (1024x1024)
