Fast Image resizeing for space saving uploads

Since I started writing this blog there has been one thing that I have been doing manually that I feel like a burden. I take pictures (8MP) of things I build, then I have to download them to my computer and then sort them. After that I want to upload them to my SkyDrive but I have limited space so I have to shrink them. I use Gimp for this, but the manual way. I have read that you can script everything but it seems too hard.
I decided to write my own application that does exactly what I need and not one thing more.
