At present you can get 32GB sdhd and micro sd flash memory cards.
how do i put my memory card in the camera, it won't fit
It depends on the camera and the size of the memory card.
The largest Memory Stick card you can use in your Sony Cybershot DSC P71 is 256MB http://www.mymemory.co.uk/compatible-memory/Digital_Cameras/Sony/Sony_Cybershot_DSC_P71
The memory card is camera specific, however the camera itself is waterproof, and that includes the SD card slot. So any card which works with the slot will work with the camera.
The largest memory card available is the Toshiba 64GB UHS104 SDXC Memory card.
This is relative to your camera's settings (specifically its resolution) as well as the amount of internal memory your camera has and the size of your memory card.
if you have a photo printer you can stick the memory card in there or put it in your camera and connect your camera to the computer
No, a memory card reader is not required if your camera has a usb cable.
To clear memory card,you could format the memory card or put in your laptop and delete it
No.
