Ok, will do.
Here's what I've found so far:
On this page: http://www.zenphoto.org/news/functions-documentation
Link "functions.php" is broken.
Link "_Image" is broken.
And on this page: www.zenphoto.org/news/zenphotos-object-model-framework
Link "Zenphoto's global variables" is broken.
I'll let you know if I find more.
