Whenever I type the URL of an image into the image viewer and hit "save", the image doesn't appear and the URL pops up in my RSS feed and replaces what was there. The title that I had in the image viewer transfers over to the RSS feed as well. When I put the URL of my image in the address bar just the picture comes up, so I think the URL is correct. What am I doing wrong?

You aren't doing anything wrong. Just a bug in the code. It's been fixed now! If you edit the Image Viewer options, they should work properly now!
