Shopping Cart intergration with SlideShowPro

Greetings! Allow me to introduce myself. My name is Grahame and I'm a photographer - my website is www.gcphotos.com.au. I currently use an application called Slideshow pro (ssp)([login to view URL]) to display my images. There are several ssp products available - I have purchased Slideshow director (web interface for image management/organisation) and the SlideshowPro Player swf which is pre-compiled([login to view URL]) . There are developer APIs for this product. Basically, I am after 4 improvements: 1. Integration of a shopping cart. I need to integrate a shopping cart on my site but I want it to integrate with slideshowpro (if possible). e.g. The following link shows my artwork ([login to view URL]). What I want is for users to be able to peruse an album (using the slideshow pro interface) select works for purchase. Here is an example where ssp has been integrated with a cart: [login to view URL] Maggento ([login to view URL]) has been suggested as a possible cart that would be good to use (open source). Users should also be able to select different options when purchasing an artwork (e.g. size/medium etc). 2. Make the site smartphone happy. I want people to be able to view/purchase items from the site via their smartphone. Now, until recently, slideshow pro was all flash. However, recently they released html5 support. 3. Create albums on the fly using tags. Basically I want to present a tag cloud (e.g. [login to view URL]) from the tags assigned to images in slide show pro director. User then selects a tag and all images assigned to that tag are pulled together into an album (that you can purchase from). 4. Documentation: I have some sister sites that are basically the same (same wordpress template/same slideshow pro) - if the process is easy enough to document I can then apply it to future sites of a similar nature. That's about it! Here's hoping you can help! Kind regards, Grahame
