It's possible the compiler is mismatching your call to -setImage: and 
is thinking you're messaging an NSImageView or something, which takes 
an NSImage. Make sure the code is importing the header of the object 
that has the -setImage: method. If that still doesn't work, then you 
might have to cast the receiver...

Unless you really know what you're doing, you should always call 
+alloc and -init on the same line.
