OK... I am banging my head now... it is still doing the same.
Is it possible to have them integrated, but not at the same time. For example sharing the same database, but under the Do you want to enable the vB3 Integration which uses your vB3 headers, footers and styles? setting, make this NO. Would I be able to do it the old way then using the showphoto.php usergroup code and defining it in photopost.php?
