Would it be possible to have a facility where someone who likes the pictures from an album downloads the entire album without going through each image?

It would be great if the files can be archived automatically of that album and then given to them for downloading. I have had many requests from people who wants to download my entire album and since each album has about 100 images, it is hard for them to go one by one.

Please let me know if this is possible because it would really help me out.

That's exactly what this function is for: http://www.zenphoto.org/documentation/functions/_template-functions.php.html#functionprintAlbumZip

Thank you. That's perfect.
