We have request form customer to enable download of entire gallery (as a single zip). Anybody tried this? It seems to be quite simple write snippet that zips directory content of that gallery to a temp file and return link (using ajax). But there need to be some kind of garbage collection of long time unused zips, on the other side reuse already created zips. Any ideas?
a: only a handful galleries: leave the files and reuse them.
b: many gallieries: create all zip files in one directory. Set up a cron job deleting files oder than xy in that directory
