why is there a little blue square box with the question mark in the middle of the place where my pictures are suppose to be??
I don't know why sometimes my pictures show up, and other times I get the little blue square with the question mark. Mostly it does that in gmail.
Can someone tell me what setting I need to use? I already reset Safari. Couldn't figure out what else to do.
