I have a Coolpix P520. When starting it up for the first time in a couple months, the camera asked me to reset the date, so I did. I later noted that doing this had also reset the photo numbers (the #s that show up when I download pics onto my computer: DSCN0001, DSCN0002, etc.) to DSCN0001). So...I just now reached some of the photos I'd saved from the first time around, and it appears that the NEW photos are replacing the old photos with the same numbers (the the old ones are going away...). Hopefully I'm explaining this matter correctly. Have you any suggestions for keeping the older photos from disappearing? Thank you, Dave McBee
