Technically it’s better to store the image outside the the database, with a path and some metadata in the database.
Image data is large, and keeping it outside database keeps the size of your database smaller. You can do day-to-day operation with ease, without worrying about the DB size and how much connection bandwidth system consumes while fetching image binary from DB.
We're marking this idea as unlikely to implement, and will be watching on how much momentum it gathers. Appreciate your effort and keep posting your ideas.
