I normally use CS2 but sometimes Microsoft Office Picture Manager works well too.
First I use the "Crop" tool to get rid of the excess image area surrounding the particular subject, in this case a truck. That way when I reduce the image size, the subject focused on is close to the same size as target image size. Lastly when I adjust the image size I make sure "Constrain Proportions" is selected.
I just threw something quick together so you could sport the new looks in your sig. At least till someone with real PS skills could help you out. I still have the .psd so if you have any requests I'll give it a shot.
