If I understood your logic, you need to:

Set onItemClickListener
save the position selected inside the listener
set onClickListener of the images inside the adapter
use the position selected to recover the imagem from the data saved in the adapter

Código setOnItemClickListener:

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        lastSelectedItem = position;
        // Set the collor of the backgroud of the row in the listView, remmember to test if the flag already have been initialized;
    }
});

Código setOnClickListener:

onClick(View v){
    // use some field thought the constructor of the adapter
    Drawable draw = data.getImage(lastSelectedItem);
    ImageView img = (ImageView) v;
    img.setDrawable(draw);
    // set the lastSelectedItem and change the color of the background
}

I hope that help you.
