Well to answer some questions...

Im getting a FUJI FINEPIX A330 DIGITAL CAMERA and it has 3.2 mega pixels and it says it has xD memory expansion...which means???

Also does it matter what kind of memory card I get?? Does it have to go with the camera??

The memory card that's the same name as my camera is $90 and it says.....
"Fuji xD 128MB picture cards are extremely compact and very economical. They are almost half the size of other memory cards yet hold 16x the capacity"

I can get a Fuji 64MB picture card for $60, how many pictures would that hold?

How many pictures do each one hold?? Can you tell?

Sorry for all the questions have never owned a digital camera, can you tell?
