I'll let someone who knows better respond about your web questions.
As far as a graphics editing program GIMP is free, but very limited compared to the other main competitors. Corel's (previously Jasc) Paint Shop Pro is a very good program you can get for about $60-$80. There's Adobe's Photoshop which is considered the industry standard and of course costs a fortune.
Personally I have Photoshop, Paint Shop Pro, and Cannon's Digital Photo Professional (to go with a canon digital camera) on my computer. Have you heard of torrents? just run a virus scan on the files first. hums innocently and walks away
