Most likely, the photos are still there.
Take the memory card to your local photo processing store.
See if they can copy the contents of the memory card to a CD ($2.00).
If not, you will need a card reader for your computer.
If you do not have a card reader, you will need to buy one ($20.00).
They are available at any store that sells digital cameras.
Install the card reader on the computer and try to read the memory card.
Use "My Computer" or "Windows Explorer" to look for the card reader (with card installed).
It will appear to be a new hard-disk.
If that doesn't work:
Then you need some "photo recovery" software.
There are hundreds of such programs on the Internet.
Go a Google search for:
photo recovery software
Here are some recovery programs that were recommended by another of our Moderators:
ZERO ASSUMPTION RECOVERY
PC FILE INSPECTOR
Search for them with Google.com
After you have recovered your photos and have them safely on your computer.
I suggest you immediately write a copy of them to a CD or DVD blank.
Then if you want to be able to use that memory card again in your camera:
Using the card reader and computer; delete all files and folders from the memory card.
Then insert the card in your camera and "format" the memory card with your camera.
Your camera has a "format" command in the menu.
"Always format a NEW card with your camera before you capture any photos on the card."
Failure to do that, can result in the problem you just had.
error message of "Memory Card Error" "Card Locked". The card's tab is not in the locked position. The 16 MB card works fine.
