How can i view my photos that i copy on my playstation 3?

May be...

it doesn't come out in my photo section

Are you sure u have copied them

and check out all the media apps and also the play list they might be hiding

If there on a flash drive, or memory stick you gotta make sure you copy it. But if none of this works for you i think something might be wrong with your ps3
