title: Reduce UIImage size to a manageable size (reduce bytes)
body: <p>I want to reduce the number of bytes of an image captured by the device, since i believe the <code>_imageScaledToSize</code> does not reduce the number of bytes of the picture (or does it?) - i want to store a thumbnail of the image in a local dictionary object and can't afford to put full size images in the dictionary. Any idea?</p>
