CMS Made Simple Forums

I just installed CMSMS and I love it, especially the photo album you've got going for it - so much easier to insert pictures/galleries than in Joomla!! But I was wondering if it's possible for visitors to comment on the pictures? I've been through the options and didn't see this (though i did only install it today!!) and was wondering if downloading a seperate module would be necessary, or if it's just not an option at the moment?

Thanks for reading this!!

P.S - this is a great CMS!!!
