@panigrah , thank you for your answer. Actually, that was my problem. I have an Express backend, and as you said, it was not set to serve static files. Now it is ! I used express.static and I can reach my static files (and therefore my images) and display them in my vue.js frontend. In fact, that has nothing to do with my database. Sorry for the off-topic. And thank you for putting me on the right track.
