How to delete pictures in built-in memory, dmc-LZ7

What happens when you format the memory card in the camera?

If you mean you want to delete them, with no card in the camera, go into the menu and find "format"...follow the on-screen instructions.

Consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program, such as Picasa ( http://picasa.google.com ).

Yes. There's a "Copy" option in the playback menu. It can copy all pictures from internal memory to a card, or individual pictures from a card to internal memory.

Remove the memory card. Go into the menu and find "reset"...follow the on-screen instructions. Then, go into the menu and find "format"...follow the on-screen instructions to erase the internal memory. Then insert your card and all should be well.

maybe the card reader is not SD/SD HC compatible, the same problem occurs wiith the Memory Stick Pro/Duo of sizes 2GB or above in my Desktop Computer (Compaq) and not in my Notebook (Compaq) the card reader and the machine are newest and are compatible

you may have to manualy delete each picture... on another not, the internal memory on the camera isn't meant to hold many pictures- i think 3 at the highest setting and maybe 9 at the lowest setting. you should buy a sd/ memory card, they are fairly cheap, and they will hold between 200 and 5000 pictures, depending on the size you buy and the setting you have your camera set on.

I have a DMC-LZ7 that I purchased a year and a half ago. You can transfer pics from the built-in memory from the "copy" menu function when the camera is in play mode (10th option down in the menu). If you move the cursor down to this selection then hit the right arrow button, there should be options to both transfer from built-in memory to the SD card and vice versa.
