Very interesting. It doesn’t accept either. Now I know why you’re not doing it the easy way. I finally get why you’re just trying to change your tiny avatar. Bummer. 🙁
I had not enabled the image posting feature because it was an easy way to keep spammers from getting in here and posting something offensive. Our anti-spam system has proven itself to be working quite well so I turned on the feature.
To post a picture, use an img tag pointing to a picture hosted elsewhere, such as your blog, flickr, picasa, or photobucket.
