I need a overhaul of my website, basically surf.warfield.net.au has a image gallery which is using the freeware program gallery2 - I need a replacement, or a easy way to:
1. Upload photos to a folder, and have them automatically update thumbnails.
2. Display a watermark over the top of every image.
3. A shopping cart with paypal account attached to it - once payment is recieved, the user recieves a zip file with full resolution files in cart without watermark.
4. A remove watermark payment, I set a price and a user can access all images without a watermark (Not Required).
5. Consistant CSS throughout site.
I would prefer if the coder could use a standard gallery like coppermine or gallery2 so I have some admin options with a lower cost.
