Make images toolbar only appear when viewing folder in image mode

I thought that there used to be a way so that the Images toolbar would only display when the folder was in image view mode, Now it does not automatically popup and hide anymore. I may be missing a setting. But I don't want it to show all the time (uses space) but I do want it to show up when I am looking at images (so I have the functions).

Help!
