Editing and Posting Screens

Up until now I have used Photoshop then Animation Shop but both of those trials have run out. I tried just editing with paint and everything worked out but for some reason I can't host paint files on ImageShack so I can't get them online. If anyone knows a free program I could use or can fix my hosting problem with paint that would be appreciated. Thanks.

All you need is a image converter. You can track one down easily with this search engine
