CPG for Iphone App

[tini]

I have an iphone app designer making an app for my site and he asked:

Ideally we need one that can output your coppermine albums in XML.
I need to be able to access the direct HTML image link and description for each photo. Then I can show it as an album and have the option to save it to the phones photo application.
My only snag is parsing the image urls from your site. Do you know of a way to ,securly, query the albums and return the image links and descripions from your image library?

Can anyone help please?
