Tento problem sa vyriesil,ale objavil sa zas povodny. Prikladam modul image.c 
z mojho programu - pridal som tam testovaciu main() funkciu. 
Hadam som mohol ten image.c zjednodusit, ale myslim ze to nie je podstatne, 
kedze vyhadzuje uplne vsetky pouzite graficke funkcie. 

Nasleduje vypis kompilacie:
