I'm still having a problem, but only from Jessica's computer.
I used the [img][/img] code, just like I've been doing for 7 years, and instead of the actual image coming up, it comes up as a hyperlink flanked by "[img][/img]".
The URL is a proper one, there are no spaces or anything to screw it up, and I tried it in both upper- and lower-case to make sure it wasn't case-sensitive.
When I used the image icon on the screen, the image itself showed up in the text box, but when I submitted the post it still came up as a hyperlink.
