We have been working on a user logon module screen, where the user will be given a user name and password to open thier chosen albums, view this on the Test Gallery page, Registered users can logon and setup test thier own users on the Test Logon page, and will be able to view a new website project we are working on, to replace our gallery

This is not a security module as SlideShowPro as a savvy user can exract the images from your website by tracing the xml source, buy that would be the 0.01% of users, most would not know how to extract an image

Watermarks are ugly and spoil the user experience, so the only advice we can give is to upload your large images at a lower resolution and optimised for the web, there are some Photoshop actions out there and even one on the Slide Show site

 We have been working on PayPal Checkout to use with SlideShowPro the Flash fla can be downloaded FREE from the download page for registered users

If you do not own a copy of SlideShowPro the basic cart script can also be downloaded 

Later we will develop a plugin for Flash to deal with multi level pricing for various checkouts, as there is little out there that deals with pricing at a Size and Finish level
