Android : Performance issue with paging FragmentStatePagerAdapter and GridView with images

I have an page with arrows, by clicking on each arrow I move to next page with grid and images there (the images were downloaded before entering to the page).

I have an performance issue that at the beginning before I run over all the collection of pages and load the images into the memory the page change is made slowly because of the images load. I wanted to ask if you have any ideas how to fix it:

So I have an PageAdapter that extends FragmentStatePagerAdapter . There I'm creating a page that extends BaseFragmentand in every page I create instance of GridAdapter that extends BaseAdapter and responsible for the images drawing in the GridView. I don't work directly with the GridAdapter because I need to return to FragmentStatePagerAdapter an fragment for the paging.

When I creating GridAdapter for each page I create the viewHolder:

private MyViewHolders createHolder() {
        MyViewHolders holder = new MyViewHolders();
        View view = LayoutInflater.from(fragment.getActivity())
                .inflate(R.layout.cust_layout, null);
        holder.layout = (RelativeLayout) view.findViewById(R.id.Rlayout);
        holder.image = (ImageView) view.findViewById(R.id.mainIMage);
        return holder;
    }

and In getView

public View getView(int position, View convertView, ViewGroup parent) {
        CarData carD = getCarItem(position);
        MyViewHolders viewHolder = getViewHolder (carD.id);

        viewHolder.carImage.setImageDrawable(carD.image);
        convertView = viewHolder.layout;
        return convertView;
    }

It all loads with 1 sec delay, after I browsed all the pages it start to work correctly.
