I have been having same issue. I will try today just to see.
This one loaded and was able to be inserted. One thing that I maybe was goofing on lately was when I c+p'd the link address it was displaying the http thing twice and then would resort to thumbnail picture, kevlar might want to watch for that.
Two others I tried were too big of a file size/dimensions and did not even load. Said it could not re-size my photo.
Any idea on how to make the picture an avatar?
