When I download my latest picture 'twilight' to my office computer it saves with .png.jpg extension. It then cannot be set as a desktop picture (windows XP). If I delete the .jpg part of the file extension, leaving it as a .png file, it can then be set. This is the first picture I uploaded using the new Upload System and it was uploaded as a .png file. Has anyone else seen this problem?
The problem was because he saved the largest size with the extension ".jpg", but the file was in fact a PNG. All the other sizes were jpeg though. The trick is in naming the file correctly, but this is pretty much up to the client to do properly. I'll have to think a bit more about this.
