Like this:
1. Add a GridView to your application.
2. Make your own custom adapter to it. For example, like this:

class MyGridAdapter extends BaseAdapter {
  
  Context context;
  ArrayList<String> items;
  
  MyGridAdapter(Context context, ArrayList<String> items) {
    this.context=context;
    this.items=items;
  }

  @Override
  public int getCount() {
    return items.size();
  }

  @Override
  public Object getItem(int arg0) {
    return items.get(arg0);
  }

  @Override
  public long getItemId(int position) {
    return position;
  }

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    if (convertView == null) {
      imageView = new ImageView(context);
      imageView.setLayoutParams(new GridView.LayoutParams(93, 93));
      imageView.setScaleType(ImageView.ScaleType.CENTER);
    } else imageView=(ImageView) convertView;
    
    ImageLoader imageLoader = ImageLoader.getInstance();
    imageLoader.init(ImageLoaderConfiguration.createDefault(context));
    DisplayImageOptions options = new DisplayImageOptions.Builder()
                                           .imageScaleType(ImageScaleType.IN_SAMPLE_INT)
                                           .cacheInMemory()
                                           .cacheOnDisc()
                                           .build();
    imageLoader.displayImage(items.get(position), imageView, options);
    
    return imageView;
  }
  
}

3. Install this adapter in your GridView:

ArrayList<String> items = new ArrayList<String>();
MyGridAdapter adapter = new MyGridAdapter(this, items);
gridView.setAdapter(adapter);

items in this case should contain a list of image URLs.
