You have to know how many samples per pixel, if stored in RGB format, BGR format, Grayscale and how to parse the file format (JPEG/BMP/GIF/etc...)

I'm using 256 colors so it's one byte per pixel

One approach is to search the internet for IJL and IPL (Intel Jpeg Library and Image Processing Library) I believe they were written in C so it should compile properly. If you are just using BMP format, IPL will be all that is required.
