How do I delete images that appear in mu Pick and image: drop down I have hundreds of options many of obsolete images

If you go to the Home icon at the top of the screen, at the bottom of that dropdown you will see files.

In files, go to the company images tab, in there you will see all the images you have uploaded and can delete from there.

Hope that helps
