How many pictures can I store?

The number of pictures that you can store depends on several variables:
The resolution of your camera. Higher resolutions mean larger files.
The type of image compression your camera uses to create the image file. Highly compressed images require much less storage space than uncompressed, but image quality suffers.
The amount of detail in the image affects storage requirements. A black car on a white background requires less space than a family grouping in front of a flower garden.
If you know the average file size of the resolution used by your camera, you can determine the approximate number of pictures you can store using a given capacity:
Divide the available storage space by the file size. If the camera's resolution results in an average file size of 200kb (approx. 200,000 bytes), and you have a 16MB (approx. 16,000,000 bytes) flash card installed in your camera, then divide 16,000 by 200 - that's approximately 80 images.
Here is an example chart showing storage capacity in relation to file size using high resolution JPEG compression. Your results may differ based on the variables listed above.
