I have pictures on the card that show up on my

Some Sony Cybershot camera's have a small amount of memory built into the camera. Double check that the camera is set to put the pictures onto the memory stick.
If the camera is set up correctly, the memory stick may not be formatted correctly for your computer. If at all possible, connect the camera to your computer directly with the USB cable that should have come with it.

the memory stick probably got corrupted and needs to be reformatted

try using a multi card reader that shoul solve the problem fast

Once it was happened to me, I went in folder options, enabled 'show hidden folder and files' option and got all pictures in memory stick that were hidden in picture folder for some reason. Selected all with CTRL+A, right clicked, clicked propertise and uncheck hidden mark
Try that, might help you.

If you put the memory stick back into the camera can you see them thru the camera menu? If so your computer's SD card port may be having issues. try using the card in another computer or use the cameras USB cable to transfer the pictures from the camera to the computer if it has one. Do other memory sticks work in the computer ok? If you cannot see them in the camera either then the pictures will be corrupted and probably cannot be recovered. Then the card will need to be formatted to erase any errors on the card. Always use the camera to format a card whenever possible...Hope that helps.

you have to get an adapter

All labels to face user. Etched out corner is always bottom left. Best to have good grip on the adapter before inserting duo card.

Get a USB card reader, insert the memory card into the card reader and then connect the card reader into the USB port of your computer.
The computer will see the memory as an external memory device, now you can view the data/images and copy them to your computer.

The memory card can't be more then 2gb...the camera won't support more than that. Have you formatted the memory with the camera? If not try that, don't format the card with your computer.

Try and format the card with the camera. Got to use the menu settings for that.
