While working in PSP, a copy saved in PSP or JPG will have the exif. A copy in Photoshop will not keep the data. I will have to check to see which files retain exif when saved through the "jpg optimizer" for web usage. I always keep an original on hand(untouched except to copy) to be sure exif is available to me after manipulations of the copy. Of course, I keep an original anyway..exif or not. I once mentioned to a distant friend(Russian man) about the camera used for the photo...surprised him! He did not know the exif came with his jpg.
