Suppose I wanted to sell advertising space on my site, could it be possible to charge for a position based on the amount they paid?

Another words, you visit the site, select the image you want to upload (form), then you would go to the paypal website to submit a payment amount of your choice (right from the form) then the ad would be placed accordingly on the site. Meaning that the ads are sorted based on the amount that was paid, higher priced ads on 'homepage' cheaper prices on higher pages into the site.

-- Or--

would I have to do the placement manually? I never looked into other scripts for this purpose as I am thinking this would be a new idea.

Thanks, and I am awaiting replies!

It would be dangerous to have an automated image adder, since random users could just hack it and post pr()n all over your site...

IDK, be safe

Personally I would not do it without a manual review process after the payment is confirmed. Yes I think it can be done safely with text links.

Allowing image uploads can present a security problem.

Thanks to both of you for the replies! That definitely makes alot of sense.

Colbyt, do you know of a ready make script for the payment / sort by price features? I already have a form ready where a user can upload the ads.
