How can you insert images into a spreadsheet and then hide them so that they aren't visible?



What I am trying to do is to create a list of the goods in my apartment for insurance purposes. I want to attach images (screenshots, receipts, photos) as evidence for the existence of each item and the cost of replacing it, but I want to hide those images so that they remain hidden until I specifically choose to view one of them. I would also prefer to embed the images in the spreadsheet rather than linking to external files in order to reduce the risk of images going astray.
