LG Rumor / Scoop / UX-260

ok i just got my new account with alltel from at&t two days ago. me and my mom both got lg scoops. i had a memory card for my old phone so i was hoping it would work. it says at the top it reads it but when i go to my pictures theyre not there cuz thats all i had on the card. is there somewhere else i need to go to find my pics or does the card just not work?
