Thanks everyone.
@sadiq6210: I'm not sure what it'd all take to get CKEditor 4.1.1 as vB's default editor. One of the first steps would probably be to compare the CKEditor 3.6.2 version in vBulletin to the stock CKEditor 4.1.1 version and see how to include YAHOO.util.stuff and vbulletin.stuff and then try it and see what breaks, find out why, edit in a fix, repeat.
@hsoen: Sorry, the images directory is a relative subdirectory to the main gallery directory.
Thanks again everyone, I hope you enjoy PhotoPlog. :up:
