ViewPager image galley out of memory

Question

I am using a ViewPager with a PagerAdapter to show one ImageView per page. The images are full screen but they are not even that large: 120-320 kb per picture and 720 x 940 px resolution.

My code is supposed to destroy the ImageView when changing pages. I am getting the Out of Memory error after when loading the 4th picture every time and crashes my app.

Why am I getting this Out of Memory error?!

My Pager Adapter

public class AvatarPickerPagerAdapter extends PagerAdapter {

    @Override
    public void destroyItem(View collection, int position, Object o) {
        View view = (View)o;
        ((ViewPager) collection).removeView(view);
        view = null;
    }

    @Override
    public void finishUpdate(View arg0) {

    }

    @Override
    public int getCount() {
        return avatars.length;
    }

    @Override
    public Object instantiateItem(View context, int position) {
        ImageView avatar = new ImageView(getActivity());
//      imageView.findViewById(R.id.avatar);
        avatar.setImageDrawable(context.getResources().getDrawable(avatarResources[position]));
//      imageView.setImageBitmap(BitmapFactory.decodeResource(getResources(), avatarResources[position]));

        ((ViewPager) context).addView(avatar);

        return avatar;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == ((ImageView)object);
    }

    @Override
    public void restoreState(Parcelable arg0, ClassLoader arg1) {

    }

    @Override
    public Parcelable saveState() {
        return null;
    }

    @Override
    public void startUpdate(View arg0) {

    }
}
