I want to integrate zenphoto with vbulletin forums , to use this on my website , some ideas???

please help i dont now how to do this .

The "standard" approach to this is to create a zenphoto theme that has the look and feel of the rest of your site.

You can use bits of zenphoto by including the template-functions.php code in your php pages. See http://www.zenphoto.org/trac/wiki/ZenphotoHacks#zenphotoasaplug-in This lets you display images, thumbs, etc. in those pages.

sorry sbillard but i need to allow only my register user can post comments only if they are autentificated. and i dont now how to do that with vbulletin forums.

some help guys??

Not sure why you are sorry, I only told you the answer to your questions on integration.

You will have to write a zenphoto "spam filter" plugin that validates your users. I have no idea how you do this with vbulletin forums.
