Right, so just use the image loop, like in any of the themes (use one as an example) and for each image, print out its link using the getCustomImageURL(...) function. That part's easy, and I thought you knew that already ;-) Just look at the themes, all the loops are set up. You don't need to "get" the album or image names, hehe
Your getCustomImageURL would look something like...
`getCustomImageURL(null, null, 768, 1024)`
The first two are $size and $width, which you don't want, so keep them null. This would go in the image loop, and would produce links to those sized images for each image in the album.
Hope this helps! I really should put up some better documentation so this stuff makes more sense...
