Pixels are a measurement of the resolution of an image. For example, old laser printers used to print in 300x300 pixels per inch, then came 600x600 prints. I'm sure you're asking "Why are you talking about laser printers when I asked about pictures?" Because the premise is the same. An image that is 1 inch by 1 inch that use the 600x600 resolution would have a file size roughly twice that of a 300x300 resolution.
All of that to tell you that no one can really tell you, you will have to find the resolution of the image, find out how many pixels are in a square inch of that resolution, then multiple it by the size image you have.
