Vbulletin help

I recently purchased vbulliten to set up a online study group for my school. It seems to have a few bugs though.

When people upload avatars or link to them, in the place where it’s suppost to show the picture it just shows a link to the picture. The same happens with footers.

The IMG tags are enabled and work fine when just posting a image. I enabled everything i could find about avatars and signatures in the control panel and still no luck.

has anyone had this problem before?
