I have created a photo hosting website. This is entirely written in php as a custom app by another GAF user.
This project will be to look through the code, and add a batch upload facility to the site. An example could like the one used in [url removed, login to view] It would allow the user to upload a directory of pictures. The autoresizing on the website will still have to work.
The upload app can be done in any language you like, or even one you have previously done.
PM for the website. You can have read only access to the code too if you like.
This is an urgent project that needs to be done.
take a look at [login to view URL] (login: test password: test). i implemented it there and can do it for your site, too.
