I've attempted a couple different times now to add an avatar image to my profile. I made sure to select "use custom avatar" (instead of "do not use an avatar"), and I made sure the size is 100 x 100 pixels. It's a jpg image. I tried entering the link for it on photobucket, and when that didn't work, I saved it to my PC and tried uploading it from there with the 'browse' feature. Each time I was told "Unable to save image." What could be wrong?
