I would say that you should mainly work on the cropping of an image so that it fits well in the thumbnail. That's one of the trickier aspects of creating custom images.

If you do want to do so, then using the free to download Photoscape and the online Punapic both allow you to create decent looking images by making backgrounds transparent, overlaying images, and cropping/rotating pictures to suit your needs.
