title: load showing image in listview with custom baseadapter
body: <p>I am working on a android project and i am implementing an adapter for my listview. </p>
  
  <p>My adapter simply load an image and a text together and show them on the listview
  but it's not efficient to load all image on cach.</p>
  
  <p>So i'm looking for a way just to load image which are shown to the user on listview and every time the user scroll up/down the images of list being update</p>
  
  <p>Is there any way to do this?</p>
  
  <p>thanks in advance</p>
