General Support: Oypo integration

Hi,
I'm software developer (fairly basic php knowledge) and photographer, and I'm fairly new to Plogger, which i found while looking for a better solution to improve the way customers can order images from my website.
To allow customers to order photographs, i use Oypo.nl's services, they provide printing and shipping of photographs, and handle all payment thingies with the customer. In return they keep a small percentage of the sold amount for themselves.
There are basically 2 options to integrate Oypo's services into ones own website:
1. Iframe : this is what I'm using now and basically displays a pre-made gallery page (hosted at Oypo's server) inside an iframe. You guessed it, this doesn't look very professional.
2. Ajax : this is what I'd like to implement, they support ordering images via an Ajax script with images that are hosted on another server than their own.
So I'd like to:
- Host small web sized image on my website inside Plogger, with appropriate links to order them at Oypo
- Host the full size images on my server at home, which will be accessible via FTP or web, Oypo can then pull the full sized images from there for printing them.

I've found several websites which have implemented just about what I'm looking for, I'm just hoping that those people are on this forum and are willing to share their modified code with me, which would save me from having to reinvent the wheel :-)
These websites are:
http://www.sportfotografie.us/index.php?option=com_plogger&Itemid=41 (plogger integrated into Joomla via component)
http://www.kooij.info/Reportages/index.php?level=album&id=7 (plogger integrated into joomla via iframe)

Any help will be greatly appreciated
