I have recently upgraded my mac, and I am pretty sure this happened when I first used my previous mac but I honestly can't remember the remedy. When on forums, and there are photos posted most of the time I just get question marks (?) in blue rather than photos. I do see some photos, but not all. Does anyone know what could be the cause for this? I know flash has to do with vidoes, and that is not installed out of the box, but what about photos? Thanks in advance for any help!
