I am trying to purchase a memory card for my Kodak digital camera, but I'm trying to differentiate the sizes..

The one I'm looking for is the small xD memory card which is just under an inch in width. My camera is the Kodak CX 7300. I'm looking on Amazo, how can I tell the difference between the size I'm looking for and the older card that is a lot bigger? Also, about how many pictures can be taken on 256 MB?

First of all the CX 7300 uses a SD type memory card.

The xD card in NOT a compatible memory card.

I don't know if they even still make 256 MB cards any more. With 2GB cards costing under $20 when on sale, I would think buying a 1GB card wouldn't set you back too much.

skip amazon....go to walmart or best buy. best buy has good deals most of the time. you don't have to worry about the size if the card if you are buying xd...they are all the same size! just as long as you buy the one that says xd...not sd or micro sd. the amount of pics you can get on the card depends on the settings you have on the camera...check your owners manual

usually it says if the card is a mini. i have a regular kingston sd car 256mg, and i can take up to 190 5mega pixels pictures. and maybe 15min of video

the camera takes the sd card
not the xD card
everything is in the manual
even how many pictures fit on a card
