file formats+discussion
There is some support for image formats now, you can just add ".jpg" and you'll get just the file, and you can still add a size like "?size=small". If you guess the wrong format, Wagn will auto-correct that to the right file ending. (It uses ".jpeg" - would it be easy to make that ".jpg" which is far more common?)
Can we get a list of the image formats we work with now?
