Is PPC right for my site? [Image Hosting]

I own and run a torrent image hosting site.
Now this site is free, so its gathering pace pretty quickly, i have added a 5 second advert window to ALL thumb clicks from the end users/views.
So when they click on the thumb should they wish to view the bigger picture or save it etc, it will head off to my site and will display a full page advert for 5 seconds before continuing to the image.
My question is what would be best for the advert window ?
I don’t think im in the position just yet to sell space, so im thinking perhaps a PPC advert ?
Your idea’s and views on this are most welcome
Cheers
RR
