Why would you need to get an existing thumbnail? You can always request a thumbnail and receive one.
Let's take https://commons.wikimedia.org/wiki/File:Virmalised_18.03.15_(4).jpg as an example. You can try hard to figure out what thumbnails already exist for that picture, but why bother? If you want a 197px thumbnail, just embed https://upload.wikimedia.org/wikipedia/commons/thumb/d/d0/Virmalised_18.03.1... /*197px**-*Virmalised_18.03.15_%284%29.jpg in your code. The part I highlighted in yellow specifies the size, and the red part is what you add to the URL to make a thumbnail.
If a thumbnail exists already, it'll be sent to you; if not, one will be created. In any case, you get a thumbnail of the desired size, and will save on network traffic.

Hey all,
I've been working on image uploading in my Javascript based extension. Although embedding local images after uploading them works fine, there's the use case of wanting to embed images already uploaded to the wiki. I could use the AllImages API and the the url's of all the images but that would be a tremendous amount of network usage compared to a world in which I can simply get the thumbnails. I know the urls exist for the images because you can "copy link address" on the thumbnail when you're viewing the file description page.
So, is there a way, using one of the many MW API's, to get the thumbnail url's for all the images?
Thanks,
