What is an image file size?

Images are made up of many small dots called pixels, and each of them has a color, a pixel representing 3 or 4 colors. Such as red, green, blue (RGB) and cyan, magenta, yellow and black (CMYB). Usually 3 bytes are used to store each of these pixels.

When a camera says it takes 5 megapixel photos, it means that each photo has 5 million pixels. If our smartphone has a 5 megapixel camera, and we take a photo with it, then that photo will have 5 million pixels and it will take 15 million bytes to store that photo. If you want to send this photo to a friend by e-mail, it will have to transfer 15 megabytes of data and it will take a while to upload and a lot of time for the recipient to download it later.
