Where are my Nokia lock screen background photos?

[nokia6300]

When i first got my 720 there were several lockscreen background photos i really liked. I did a phone reset because i had to reset my outlook account and i've upgraded to Amber. Now i have a different set of background photos. Did either one of these actions cause my original set of photos to be replaced by this new set i have? How can i get those photos that originally came with the phone?

different firmwares and updates have different photos , you can flash your phone to the firmware you had before or try googling im sure they are somewhere out there
