I notice that `imageNumber()` returns new incrementation in each album. Is there a function to return the actual zp_images/id field?

`imageNumber()` returns the number in the row the image has which is of course different related how you sorted your images. Use this: http://www.zenphoto.org/documentation/functions/_template-functions.php.html#functiongetImageID

Thanks, MM, just what I was looking for!
