title: How to resize the image programmatically in objective-c in iphone
body: <p>I have an application where I am displaying large images in a small space. 
  The images are quite large, but I am only displaying them in 100x100 pixel frames.
  My app is responding slowly because of the size fo the images I am using.</p>
