caching images that are retrieved

Question

Hi, I am retrieving a list of images and text from a web service. The images are getting displayed in the list view. But the problem is, when i scroll down the list the entire images are getting loaded once again. When i scroll twice or thrice there is a OutofMemory occuring... Can anyone tell me how to cache the images and also to avoid the loading of the images that are already loaded when i scroll down. I have tried to increase inSampleSize but it didnt work... Here's the code....

public static Bitmap loadImageFromUrl(String url) {
    InputStream inputStream;
    Bitmap b;

    try {
        inputStream = (InputStream) new URL(url).getContent();
        BitmapFactory.Options bpo= new BitmapFactory.Options();
        b=BitmapFactory.decodeStream(inputStream, null, bpo);
        b.recycle();
        bpo.inSampleSize = 2;
        return b;
    } catch (IOException e) {
        throw new RuntimeException(e);
    }

//  return null;
  }
