Download images in "zip" format without binary zip file available

Hi
Is it possible to download photos from cart in form of zip file? I've tried to use module "Zip Download 1.0.5" but it requires access to zip file which I don't have (gallery is placed on virtual server hosted by external internet provider). I've tried another gallery platform - zoom media gallery for mambo. It can easily compress photos to zip file without application zip installed, but it lack some futures which gallery2 has.
Regards
Martin
