I have posted over 400 photos I've taken during hte playoffs on my site - http://www.cavsworld.com - a few of these are high enough quality that I think I could sell reprints of them. Standard photos, posters, mouse pads, etc.

I tried as an experiment setting up 1 page with 1 photo on cafepress, but they took the page down. It is my understanding that I own the rights to resell copies of photos I take at public events and that there was legal precedent to support this. I thought I finally had found a solution to how to generate some real revenue from my site.

What I'd really like to do is give people the ability to order prints, posters, etc directly on the page they view them and have them collect in a shopping cart and get routed to a 3rd party to print and ship them.

Alternately, I would like to be able to pick a dozen or so images and crop them to the sizes needed to generate the various sizes of prints/posters/etc instead of doing it for my whole photo library. Those could be done off site through a service similar cafepress.

Is there a viable solution to either of these approaches given the content on my site. It is all my own original photography of public events.

Please look a little more into the copuright stuff first - some public events will not allow you to generate income from photos you take...

Then do a bit of poking around and searching on the various shopping cart modules - provided you are not going to breach any laws. This is good research to choosing a module - there is an FAQ on this.
