	struct iPict R; allociPict(&R,zHt,zWd);
	struct iPict G; allociPict(&G,zHt,zWd);
	struct iPict B; allociPict(&B,zHt,zWd);
	//dithering
	pixelFunction(&R,&G,&B,zHt,zWd,0,0,0);

the 'struct' calls will always be clean to me. It will load an 800x600 image without segmentation faults. The next call will trigger segmentation faults.
