I don't understand that... I integrated Photopost and Reviewpost successfully with vBulletin, but RP is still using the images from the RP-Dir (in my case, it's the "Post Reply"-Button that i replaced as told above)... Headers, Footers, Styles... All the rest are looking fine.
Why should it not be possible to add a Graphic for the "Post a review"-Option. That really woul help !
@crsicokid: Do you have instructions how you "hacked" RP that way? Sounds interesting...
