Thank you, I will give it a try.

Purge the queue that is filled by your background process.
List item views (and imageviews within your list item views) are
recycled. Remember for which list-item (or image-view) the
background-thread is loading a bitmap (you'll know this in the
adapter's getView method). Later, as soon as the same image-view is
re-used for another bitmap, look-up the loading of the bitmap that was
previously to be assigned to the image-view and remove this bitmap
from the cache. For good measure, call 'recycle()' on it. Then start
load the new bitmap for the recycled image-view.
Instead of immediately purging unused bitmap, you may want to hold on
to them a little longer so that your background doesn't need to
re-load the same image over and over again. However, this will
increase the size of your queue. You'll have to put a limit on the
queue (never more than 'x' bitmaps in the queue).
Also be sure to load bitmaps that are at most slightly larger than
your image-view (BitmapFactory.Options.inSampleSize > 1). Don't load
full-sized bitmap if it's not absolutely necessary.
