RE: Cron

using 'find' is another way of doing this.

make a script that gets run by cron that has a line similar to the
following:

find /tmp/images -amin +60 -exec 'rm {}'


This assumes your tempimages are saved under /tmp/images. Also, I have not
tested this, and i've never before actually used the -amin or -exec
parameters, so they may not work properly. check find's man page for info.

Hope this gets you in the right direction.

Andy
