I an using this method:

public static Bitmap getLargeImage(String imgUrl)
    {
        Bitmap bitmap = null;               
        InputStream in = null;
        Log.v(TAG,"start fetchimg main images");
        try
        {             
            DefaultHttpClient mHttpClient = new DefaultHttpClient();

            HttpGet mHttpGet = new HttpGet(imgUrl);

            HttpResponse mHttpResponse = mHttpClient.execute(mHttpGet);

            if (mHttpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) 
            {
                HttpEntity entity = mHttpResponse.getEntity();           
                if ( entity != null) 
                {
                    in = entity.getContent();

                    BufferedInputStream bis = new BufferedInputStream(in, 8190);

                    ByteArrayBuffer baf = new ByteArrayBuffer(50);
                    int current = 0;
                    while ((current = bis.read()) != -1) {
                        baf.append((byte)current);
                    }
                    byte[] imageData = baf.toByteArray();
                    BitmapFactory.decodeByteArray(imageData, 0, imageData.length);
                    if(in != null)
                        in.close();
                } 
            }                     
        }
        catch (Exception ex)
        {
            Log.v("Error Fetching images from url",ex.getMessage());          
        }
        return bitmap;
    }

    Do you receive images in different threads? If yes, which class do you use to download the images? Standard HttpClient is not thread-safe, you should use ThreadSafeClientConnManager to get thread-safe one.
