A couple of days ago, Alice Keeler (@alicekeeler) published a post (Google Sheets: Embed an Image) about the =IMAGE() function to insert images into a spreadsheet. It is a function that allows you to embed an image that is public on the Internet inside a cell. I encourage you to read her post.
With this function you can only embed images that are on the internet in a public way. But what if we want to insert photographs that we don’t want to publish? For example, what if we have created a pupil tracking sheet and we want that their pictures appear? In this article I show an option that can complement Alice’s article.
