The hide/show background image button is just a few pixels to the left of the delete background image button.
When I need to toggle hiding and showing the image (my eyes go off the hide/show button and watch the image alignment with my model), I sometimes hit the delete because my mouse will creep a few pixels to the right. Then I have to load, align, resize, move and rotate the image all over again every time this happens!
Is there an image lock add on, feature or any workaround to stop or prevent this?
