Trying to make a sig picture (as you can see), the only program I have that lets me crop images (that I know of) is Roxio PhotoSuite. But I've noticed that as I crop an image down it gets blurrier and blurrier. Trying to fix the sharpness afterwards through Roxio helps somewhat, but it's not as clear as it was before I cropped it. This image of Kapler, Damon and Trot was VERY clear when I started, now blurry (and I didn't save the original

)
Any advice, oh picture masters?
