title: Blurry UIImages
body: <p>I have a problem when trying to display small (16x16) UIImages, they appear a bit blurry.
  These UIImages are favicons I download from different websites and I have compared them with some images from other apps and they're blurrier. </p>
  
  <p>I'm displaying them on a custom UITableViewCell like below :</p>
  
  <pre><code>NSData *favicon = [NSData dataWithContentsOfURL:[NSURL URLWithString:[subscription faviconURL]]];
  
      if([favicon length] &gt; 0){
          UIImage *img = [[UIImage alloc] initWithData:favicon];
  
          CGSize size;
          size.height = 16;
          size.width = 16;
          UIGraphicsBeginImageContext(size);
          [img drawInRect:CGRectMake(0, 0, size.width, size.height)];
          UIImage *scaledImage = UIGraphicsGetImageFromCurrentImageContext();
          UIGraphicsEndImageContext();
  
          cell.mainPicture.image = scaledImage;
      }
  </code></pre>
  
  <p>Is there anything wrong with my custom UITableViewCell or the way I download the image ?</p>
  
  <p>Thank you.</p>
  
  <p>[EDIT 1] : By the way, .ico and .png look the same.
  [EDIT 2] : I'm working on an iPad 2, so no Retina display.</p>
