annotate gpp/forums/views/attachments.py @ 492:3c48a555298d
Added a custom tag to display a link to a profile. Refactored the avatar tag to optionally display a profile link around the image. Removed the width and height attributes from the avatar image tag. I think this was causing disk hits whenever those properties were not cached. The avatar tag is now an inclusion tag.
