title: Performance problem about showing images
body: <p>My problem is i have 50 images each is 157X157 pixels and take 25kb.They are connected to a slider and when the user slides the slider they change 0 to 100. It works but my problem is iphone 3g and 3gs is very slow its hard to see the images and sometimes it stuck for a second to show the next image. I use UIImageview to show the images.How can i do it better so the phone that before retina display can show them without stucking? Thanks for answers and your time.</p>
  
  <p>edit: All pictures is in the file they are not taking from url.</p>
