Well, picking the color is something you can do by yourself.
Skipping is just a simple 'if'


if( value != 255 )
	screen[ptr] = value;
	
instead of just

screen[ptr] = value;


I don't know what your code looks like exactly, but this is a simple example.
If you can send me the complete bmp loader, I will tell you what to do.
Btw. It might be a better idea to send the code to my email address instead
     of the mailinglist/newsgroup.
