Pictures?

Ok, so for some reason some of my pictures aren't showing up and it's making me really sad.

I know its because I cheated. I copied & pasted the picture instead of saving it. But I couldn't help it! This stupid computer just decided to take the "Save picture as..." option away from me! I swear it was there last night...

Can someone help me? Why can't I save pictures? I have a Mac. (In case you need to know) And yes, I'm still using Safari...I'm so lazy and haven't gotten around to downloading Firefox yet. (Shame on me!)

Thanks tons and bunches for the help!
