peeknpeak thanks for your post

This is a common issue with Photopost or what was previously named as vbAdvanced Gallery. To solve this issue, please edit the template header and footer, and write the full path for images. For example, instead of images/FH_Safy/image1.gif , this should be:
http://www.your-domain-name/forums/i...afy/image1.gif
This problem happens because Photopost requires installation in a folder outside the vBulletin root folder.
