1. Find out if you can actually load the image:
</font><blockquote><font size="1" face="Geneva, Verdana, Arial, sans-serif">code:</font><hr /><pre style="font-size:x-small; font-family: monospace;">NSImage *myImage = [NSImage imageNamed:@"flagged"];
NSLog(@"image: %@", [myImage description]);</pre><hr /></blockquote><font size="1" face="Geneva, Verdana, Arial, sans-serif">2. Find out if the NSImageView instance actually exists and can be talked to. Log its description, or set its bezel style, or ask for some attribute it has and log that.
One possible problem that comes to mind is that you might be loading the nib more than once: are you manually loading the nib via loadNibNamed:? Are you sure you go through that code path only once?
