actually, I think I may have found a way to function with that flickrslidr, thanks for the suggestion!

Back to this mod, I'm using it (successfully!) with picasaweb slideshows. Would there be any way to disable the X function, or the exit from within the slideshow so they CAN'T navigate from there? I'd like to come up with some sort or "exit=false" command or something so they can't exit the slideshow and browse the other picasaweb sets of that user.

You're welcome... if you got it working you should release it as a mod.

As for the picassa exit it's very unlikely you'll be able to disable the exit, picassa would have needed to be programmed with that option on google's side- the place to ask would be on a picassa forum as there are much more likely to be experts on the subject there... also would look for any picassa programming api info, maybe they've documented some extra features.

oops... nevermind on the picasaweb slideshow... They're just a little slower than Flickr to alert me they don't like embedding with iframe. It's disabled the next day, as Flickr's was disabled 1/2 second later. lol

I'll check the picasa forums, thanks for the advice.
