is there a way to load drawable to Imageview as soon as item shown on listview

Scroll grid view with plenty amount of local Images make my app crashes in devices have small amount of RAM with message java.lang.OutOfMemoryError or at-least in good performance devices it's scroll very Barely and with lag. I goggled for solution and find some good solutions are exist for remote Images like: Universal-Image-Loader that loading images from web and cashes them and manage scrolling. but I couldn't use that on my case.

this is my adapter that load images:

public class MyAdapter extends ArrayAdapter<StructureCase> {

    private LayoutInflater mInflater           = null;
    public Context         context;
    public Class           distinationActivity = null;



    public MyAdapter(Context context, int textViewResourceId, List<StructureCase> objects) {
        super(context, textViewResourceId, objects);
        mInflater = LayoutInflater.from(context);
       // mInflater = (LayoutInflater)G.currentActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    }

    public static class ViewHolder {


        public ImageView gem_img   = null;
        public TextView  gem_name   = null;      


    }



    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;
        final View v;

        final StructureCase item = getItem(position);

        if (convertView == null) {


            convertView = this.mInflater.inflate(R.layout.my_grid_list,  null);
            //mInflater = (LayoutInflater)G.currentActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = mInflater.inflate(R.layout.my_grid_list, parent, false);
            viewHolder = new ViewHolder();
            convertView.setTag(viewHolder);


            viewHolder.gem_img = (ImageView) convertView.findViewById(R.id.imageView_mygrid_list);
            viewHolder.gem_name = (TextView) convertView.findViewById(R.id.textView_mygrid_list);           
            viewHolder.gem_name.setTypeface(G.typeFacePrs);



        } else {
           viewHolder = (ViewHolder) convertView.getTag();

        }




        viewHolder.gem_name.setText(item.g_name);


        int id = G.currentActivity.getResources().getIdentifier(item.g_image+"_tmb", "drawable", G.currentActivity.getPackageName());


        if(id != 0){
            Drawable drawable = G.currentActivity.getResources().getDrawable(id);
            viewHolder.gem_img.setImageDrawable(drawable);
        }else{
            viewHolder.gem_img.setImageResource(R.drawable.gem1);

        }


        viewHolder.gem_img.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent i = new Intent(G.currentActivity, GemDetaileActivity.class);
                i.putExtra("id", item.g_ID);
                i.putExtra("content", item.g_text);
                i.putExtra("name", item.g_name);
                i.putExtra("name_en", item.g_name_en);
                i.putExtra("image", item.g_image);
                i.putExtra("image_count", item.g_image_count);
                i.putExtra("hadis", item.g_hadis);
                i.putExtra("good_for", item.g_good_for);
                G.currentActivity.startActivity(i);
                G.currentActivity.overridePendingTransition(R.anim.in_left_2_right, R.anim.out_left_2_right);

            }
        });


        return convertView;
    }

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

I think my problem is for pre-Loading all Images and if there is a way to load Drawable to Image view as soon as show it's item in scroll, my problem will solve.
