Having scoured the net for over an hour, I've not managed to find a suitable mod for VB 4.0 which enabled users to upload their photo's from online services such as Photobucket and then have the EXIF data displayed within the forum under or next to their photo post.
Surely numerous users and owners of Vbulletin photography related forums would love to have this feature integrated on their forums which would allows them to see such imfo like shutter speed,aperture,ISO etc.
