I would never do image analysis on JPG images. Why? They just have at least some information thrown away, unless you're using JPEG2000 and the lossless option. But because of legal/patent infighting it's never caught on. It looks like PNG is becoming pretty widespread and a de facto standard. It's lossless compression and only takes up about a third of the space of the full, uncompressed versions. Whenever I have to save new images I use PNG format. Recalling a JPG image and using it could give bad results if the notorious jpeg block artifacts are severe.
