If you have a memory card in the camera, all new photographs go onto the memory card.
If you do not have a memory card in the camera, all new photographs go to internal memory.
To delete all photos from internal memory, remove the memory card and either delete the pictures you see using the menu or format the internal memory using a menu command.
Be sure to save any pictures (you want to keep) to your computer, before you use delete or format.

Do I delete photos/video on the internal memory for my digital panasonic lumix camera in the same manner as I delete photos on the memory card? Do I have to remove the memory card first? It looks like I've deleted all the photos on internal memory (everything says "no image found") but I'm wondering if I have to remove the memory card first. The camera has different settings, "auto" always goes to memory card but if I accidently change the setting it can save to internal memory. Thanks!
