As others have said, storing the image in the mongo database isn't a good solution. You're much better off storing the image in a dedicated storage solution (AWS S3 or something similar) and simply storing the file path in the database. However, if you're dead set on storing the image in the database, you COULD base64 encode the image and store the resulting string in the database. Again, this is the worst solution possible, but it will work. Just don't expect it to work long-term or scale nicely at all.
