DrawImage delete - PySimpleGUI

Need help with deleting only one DrawImage on my canvas in PySimpleGUI. Canvas is loaded with a background image (100% of the canvas), and has 5 other DrawImage items on it (various sizes). When I click on one of those 5 images, I want THAT to be gone (deleted), but the background image to stay.

Using get_figures_at_location with coordinates derived from mouse click to delete the one image I want to go away. But my routine also deletes the background.

Any ideas? Could not find a way to do it after searching numerous forums.

Save the id returned when you draw background image by using draw_image, delete it after you confirmed it is not the background image by the id.

draw = window['-GRAPH-']
bg_id = draw.draw_image(filename=filename)

...

figures = draw.get_figures_at_location((x, y))
if figures and figures[0] != bg_id:
    draw.delete_figure(figures[-1])    # index -1 for last one or top one

Following code show to delete all figures after mouse clicked on the figures. (Remember to replace it with your background image)
