This of course is a good solution. What is necessary are two things:

A good documentation how to use this, and for Windows users who will not
know a programme that outputs rgb data, a clear description how the input
file format looks like. For example, the file starts with two 8-bit
unsigned ints containing the resolution in x and y direction, every pixel
contains of three 8-bit chars for rgb, ...

But this should be done by somebody who knows the image code.
