different style / template for different url somehow?

[djsteve007]

I have three styles installed, and I would like to have it so that if someone goes to:
mysite.com/forum
then they have the default regular style or whatever.. But I would like to have another page on my site pull the forum into a frame, in the third style / skin, which has been made to be very small (480px).

Is this possible?
Basically having vbulletin choose the skin based upon with page of my site they are coming from? Or just have the default style on the /forum/ and then have it so if someone goes to my split page, (mysite.com/photosforums.html where I have my photo gallery on the left hand iframe, and pull the fourm into the right hand iframe, that would change to the other 480px skin theme?

I hope this makes sense, and there is a way to do it.

I had sifted through about 300 pages in various searches, and seen a few similar questions, but not exactly this, please bear with me if this has already been figured out, please point me to the thread.
