Answer 1

you can't "pass Picasso" to the adapter. You have to create your own custom adapter, it's not as daunting as it sounds. It may even be based on the SimpleAdapter. Like this:

public class MyAdapter extends SimpleAdapter{

   public MyAdapter(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to){
      super(context, data, resource, from, to);
}

   public View getView(int position, View convertView, ViewGroup parent){
      // here you let SimpleAdapter built the view normally.
      View v = super.getView(position, convertView, parent);

      // Then we get reference for Picasso
      ImageView img = (ImageView) v.getTag();
      if(img == null){
         img = (ImageView) v.findViewById(R.id.imageOrders);
         v.setTag(img); // <<< THIS LINE !!!!
      }
      // get the url from the data you passed to the `Map`
      String url = ((Map)getItem(position)).get(TAG_IMAGE);
      // do Picasso
      Picasso.with(v.getContext()).load(url).into(img);

      // return the view
      return v;
   }
}

then you can just use this class without the image on the parameters (but it must still exist inside orderList).

ListView list= (ListView) getActivity().findViewById(R.id.list);
ListAdapter adapter = 
       new MyAdapter(
                getActivity(),
                orderList,
                R.layout.order_usa_row,
                new String[]{TAG_PRICE,TAG_TITLE,TAG_PSTATUS,TAG_PRICESYMBOL},
                new int[]{R.id.price,R.id.title,R.id.pstatus,R.id.symbol});
list.setAdapter(adapter);
