I have a suggestion for a modification which I would admittedly pay an outrageous amount of money for: An Image Management system. Basically, something I can use similar to Wordpress to EASILY upload a picture, and have it create thumbnail, small, medium, and large versions for me to use in posts and CMS content. A good customizable image resizer thrown in for pictures already posted on the site would be just gravy on top of that. I'm sick of having to resize pictures myself if I want to keep pages from bogging down with some users' connection speeds, not to mention that as attachments you have to include the attachment link or the image will be deleted. I just plain hate the current vBulletin system for this right now
