    try next (all of them or several):

    Reduce thread pool size in configuration (.threadPoolSize(...)). 1 - 5 is recommended. Use

     .bitmapConfig(Bitmap.Config.RGB_565)     
    

    in display options. Bitmaps in RGB_565 consume 2 times less memory than in ARGB_8888. Use

    .memoryCache(new WeakMemoryCache()) 
    

    in configuration or disable caching in memory at all in display options (don't call .cacheInMemory()). Use

    .imageScaleType(ImageScaleType.IN_SAMPLE_INT)
    

    in display options. Or try

    .imageScaleType(ImageScaleType.EXACTLY).
    

    Avoid using RoundedBitmapDisplayer. It creates new Bitmap object with ARGB_8888 config for displaying during work.

    make sure you make Image size as require in Your ImageLoader

    // decodes image and scales it to reduce memory consumption
        private Bitmap decodeFile(File f) {
            try {
                // decode image size
                BitmapFactory.Options o = new BitmapFactory.Options();
                o.inJustDecodeBounds = true;
                BitmapFactory.decodeStream(new FileInputStream(f), null, o);
    
                // Find the correct scale value. It should be the power of 2.
                final int REQUIRED_SIZE = 70;
                int width_tmp = o.outWidth, height_tmp = o.outHeight;
                int scale = 1;
                while (true) {
                    if (width_tmp / 2 < REQUIRED_SIZE
                            || height_tmp / 2 < REQUIRED_SIZE)
                        break;
                    width_tmp /= 2;
                    height_tmp /= 2;
                    scale *= 2;
                }
    
                // decode with inSampleSize
                BitmapFactory.Options o2 = new BitmapFactory.Options();
                o2.inSampleSize = scale;
                return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
            } catch (FileNotFoundException e) {
            }
            return null;
        }

    Set .resetViewBeforeLoading() in DisplayImageOptions.
