Images Wont Save to Memory Card

Nokia 3120....installed the micro sd card but I cant get the images to save to the card, I went through all the options to see if there was a box to select/tick but nowt.

To kinda test the card I moved some images to it and they were there and opened up perfectly.

I doubt this but do some phones have to use up the phone's graphic memory first.......before transferring over to Memory Card?

On my Nokia (e75),when you turn on the camera,press options then select memory in use
