Here’s the quick and dirty method:

NSData *imgData = [NSData dataWithContentsOfURL:URL];
cell.imageView.image = [UIImage imageWithData:imgData];

If you want to keep using your network queuing stuff, you’ll have to do that stuff in your imageFetchComplete method and use something like this:

NSData *imgData = request.responseData; 
//I think that's what the property's called. It's in the documentation

UIImageView.image = [UIImage imageWithData:imgData];
