Saving d/l'ed pics from here

Something changed about the time I said the pictures were blurry the other night. Same deal on FBBO. I can save pictures, but then you can't open them. BUT... I can post the "unopenable" saved picture to my Facebook page and then right click it and save it again and it's back to a normal jpg that I can once again open on my computer and print out if I want a hard copy. Then I delete my Facebook post..
