Bummer Deb.
I am especially disheartened to hear about your bad experience with Adobe. Pretty much just salts the wound.
If you are so inclined, you might try
"App Zapper" and do another reinstall.
Its been a while since I have used this program, but as I recall, you can download the trial version and you get so many "zaps". My trial came with five, of which I have used four, but its an older version. Then if you want to keep it you must purchase it for the price of $12.95 USD. It is widely regarded as one of the best programs (for Mac) to get rid of the files that the built-in app uninstaller leaves behind and for the twelve bucks I consider it a pretty good deal. When my trial runs out, I'll make the purchase. It works.
Deb, I'm not a big fan of MacKeeper, but if I'm not mistaken, it too has an uninstall function that might help sine you already have it on your machine.
If it is as Frank mentioned and a problem with the files themselves, and PS itself created these problems and somehow imbedded these problems, then maybe even a clean install would still "see" the problem. I would guess that, in that case, you have to repair these files.
Again, as Frank mentioned, have you tried viewing your .jpg's in another image viewing program? Say, such as Preview?
Something else that occurs to me? Do you have any back-up copies of these files from when Adobe was working properly? If so, you might try to open one or two with the Bridge and see if the problem persists. That might tell you if it is a problem with the files or the software.
