Question: How many photos can I save on the 32 MB memory card that is in our school’s digital camera? Is there an easy way to figure out how many images we could fit on a larger card if we find funds to purchase a new one?

The IT Guy says:
The number of images you can save on a memory card with a given memory size depends on the resolution of each image captured by the camera. Generally it is best to capture images at the highest resolution possible, but if you have a small memory card this can limit you to a much smaller number of saved images.

A good chart showing approximate numbers of images that can be saved on a given size memory card (32 MB up to 4 GB) is available on Lexar Memory Cards Look for the row that corresponds to the megapixel description for your camera: from 2 to 6 megapixels.
