Adding a "delete on" option to a photo gallery web app

[MBony]

I have a photo gallery web app that I would like to add this option to. When users upload the photos they have the option to say how long it will stay on the server. They can specify a specific date or just say it is temporary and have it delete the album in 30 days. It is written in php.

Similar to what drop.io does.

Ok, so what are you asking? How to do it? Any time you need something to happen out-of-channel from a typical user request, you have two basic options: 1) have a service or process that is scheduled to kick off periodically and check for matching conditions, then perform the task; or 2) occasionally hijack a user request and use that to perform the maintenance. If the maintenance is very simple and fast then (2) might be acceptable, otherwise it's (1).
