In order to give this website some nice backgrounds in the banner session on the homepage, I had to fiddle around with some nice pictures from my photo archive. It had been a while, so I looked for the freeware I knew from years back called "pain.net". It is still there and it has all the features you need for small projects like these.
In my search I also stumbled upon GIMP. That is what you call impressive software! It's free open source software but has more than you could dream of. For those of you who need a bit more I would definitely recommend installing this (or using the usb version). The site also has lot's of video tutorials explaining how to to the basic and more advanced edits to your photos and pictures.
