I know there are a host of similar scripts out there, but I like the one used at kittenwar.com.
They did a good job by having friendly urls. The only thing extra I would like is to have each photo have the ability to have its own title. This could be pulled by using the photo id number and a name that the user lists for the photo. Would possibly like to have a short description that could be added with each photo as an option. Thanks.
Payment will be held in escrow and released when a fully functioning script is up and running on my server. Thanks.
