No vB intergation?
 

If i see some Boards with your Skripts, there is no complete integration in vB.
Photopost is a seperate side... in the vB Board, there is no Thread to see.

Is there a way to display the Threads from Photopost/Reviewpost in the Boards as a normaly Post? And if i click on the Thread, then i comes to the Photopost- Board?

No sorry that is not integration. Integration is the look and feel and user authentication, Your vb and photopost are both full featured applications they dont show on the same page they show in there own directories
