Yes you were right, Changed my working directory. Thanks.
Hey, last time I programmed something was over a year ago; I dont recall having too much of a problem.
When I draw_sprite from a file, this case "small.bmp", and I execute the .exe it crashes.
If I comment out draw_sprite( buffer, Newgame, 200, 200); it works fine...
Whats the problem??

The standard advice: add checks to loading the bitmap, like:
Newgame = load_bitmap(...); if (!Newgame) { allegro_message("Unable to load bitmap."); }
That way, you'll get some information on why your program is crashing if it is something wrong with the path.
As far as I can see, there are no other errors in your code (some bad practices, sure, but no errors per se), so there is a good chance your program just can't find/load the "small.bmp" file.

That tells me the small.bmp didn't load correctly, do some error checking.

Beaten.
Whoa quick reply!
The strangest thing. There is acctually nothing wrong with the program...
When I exicute the .exe within Microsoft Visual C++ 6.0, it says it cant load the image. If I do it manually it works? How annoying?!
