For some totally unknown reason the GD library that runs some of the site's image functions deleted itself last night and now refuses to be put back! To combat this issue i've transferred over to the Imagemagick library... which does exactly the same. The only real difference users will notice is that registration no longer displays the picture-string (which I have consequently had to disable). Its a minor annoyance, but i'm sure it won't bother you all too much. I'll just leave things the way that they are until the next revision of Biorust, when I intend to give us a clean install anyway...
