Android :: Web Image Loaded By Thread

I have an extended BaseAdapter in a ListActivity: private static class RequestAdapter extends BaseAdapter{ and some handlers and runnables defined in it

CODE:.......

In the getView function of the Adapter, I'm getting the view like this:

CODE:..........

and the image is getting loaded this way:

CODE:.................

Now, the problem I'm having is that if there are more items that need to display the same picture, not all of those pictures get displayed. When you scroll up and down the list maybe you end up filling all of them.

When I tried the commented out line (holder.avatar.setImageBitmap...) the app sometimes force closes with "only the thread that created the view can request...". But only sometimes.
