How do you get pictures on the ps3 from an sd card?

May be...

I put them on the sd card but when i put it in the ps3 it says there are no pictures

put your sd card into the sd port on your ps3 its on the side.

when you put the sd card into the ps3 instead of clicking with the x button when you see the sd card, use the triangle button. It should give you a "display all" option, then you should be able to get to your pictures.

put sd card in slot.. then press [triangle]

Highlight the SD card and press options (triangle). Select display all to bring up all photos and folders on the card.
