I have recently been using photo dub and wondered if there were any other programmes like it to download free? as photo dub is only free for a trial period

I'm not familiar with Photo Dub but maybe this (http://www.gimp.org/) will suit you.

Can anyone tell me if this is still available. I have seen sites offering to download for free but read there was a problem doing this.
I found it ideal foe editing.
Thanks for any help.
