I've searched this forum, so sorry if I've missed posts that address this problem.
When opening photos that I've gotten from other members of our family via Facebook, or sometimes otherwise, it's not uncommon for me to get an error message "Could not complete your request because of a problem parsing the JPEG data".
Out on the net, others have suggested to open the photo in Microsoft Paint and save the photo from there, then open it in PS. That works, so is that the best solution when encountering this problem?
