OK, I tried this:
NSURL *url = [NSURL fileURLWithPath:fname];
CGImageSourceRef source = CGImageSourceCreateWithURL((CFURLRef)url,

CGImageRef image = CGImageSourceCreateImageAtIndex(source, 0, NULL);
CFRelease(source);
theView.layer.contents = image;
and now I get an incompatible pointer type warning on the last line.
But the CALayer contents property has an id type.
change your line of code to:
theView.layer.contents = (id)image;
And in any case, why is putting an image on a layer such an involved
process?
pardon me, but why do you think that typing 3 lines* of code is an
"involved process"? Is there something about ImageIO or the exact
nature of a layer's content that you don't understand or was not clear
in the Core Animation Programming Guide?
curiously,

* the CFRelease() doesn't really count... it's memory management and
doesn't really (directly) affect the layer content.
