Image format, bit depth (8, 16, 24, 32...), and color range will impact the file size of an image. Any answer provided based on 50kB alone will be a wild guess.
So, here is a wild guess, 300,000 pixels. It assumes .jpg at 24 bit color depth. This is a very common format and quality used to store digital images.

A pixel is a dot on the screen. These don't have a fixed size - even on the same monitor, a pixel may be larger or smaller, depending on the selected resolution.
30kb = ? pixel?
A pixel is one colored dot. in blk & wht one dot will do, but in color you need three.
256, 8 bits per pixel = 2^8 colours.
You don't count the pixel shaders. It's probably Pixel Shader 1.0 or nothing due to the horribly outdated graphics card you got.
