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?
256, 8 bits per pixel = 2^8 colours.
A pixel is one colored dot. in blk & wht one dot will do, but in color you need three.
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 It's probably Pixel Shader 1.0 or nothing due to the horribly outdated graphics card you got.
