Another great photo program that is totally free - and with no popups or spyware or any of those other pesky little things some freeware comes with - is PhotoFiltre.
It's very easy to use - just choose the English version to download - and even the additional plug-ins, etc are free for downloading. (And it's not a 'huge' program that will take up scads of space in your computer either).
Takes seconds to add any colour 'border' of your choosing, has 'auto fix' features and is actually fun to use - and very easy to learn.
I have 9 photo editing programs on my computer - some for graphics and some for photos and some specialized for certain things ... but this the one I use the most for quick 'auto repairs' and adding soft-edges, frames, etc.
Hope you enjoy trying this program out.http://photofiltre.free.fr/frames_en.htm
