If you are talking about JPEG 2000, I would agree. I still find that adding annotations on a JPG (unless one uses no compression), leaves artifacts, which are especially noticeable when they get scaled. If you are not scaling and not annotating directly on the image, then JPG is probably not a bad choice. (And yes, I agree that FM needs to improve it's handling of PNG colors. FM10 seems to have eliminated most of that problem (in that I've not noticed it in FM 10), but I've also not pushed the limits. (I also save in indexed PNG, which may have something to do with it.)
