Yes of course. Many websites still use DB, because the application itself is built with DB.
Files Gallery and Embed does not use database, because 1. it doesn't need to, 2. it's a simple passive app that can simply read existing folders. No install. No maintenance. Just because Files and Embed does not use DB, doesn't mean that other applications should not use database.
However, you are asking Files and Embed to support database, not because its practical, but because you want to read database entries creates from another application. This is not possible, because Files would have to be rewritten to suit that other application. That's like asking that other application to support Embed.
Besides, it's not like images are inside a database. The database is constructed and named specifically for the other application (some community forum website?). You can't just "support mysql" ... It needs to be setup to support a specific mysql format.

Only because you want to re-use the data stored in your existing application, which Embed does not know about.

I'm not quite sure what you mean. Regardless of mysql or non-mysql, you still need to store ALL images on disk. If you have 10.000 images in a single folder, or have them spread into folders, what's the difference? With mysql, it means you need to create hash-based names "i435uyt.jpg" etc, else names will crash.
Ultimately, both Files gallery and Embed are built to support images uploaded into a folder, without being locked to a database. That means it does not have to "install" and it means you can move files on server without breaking the application. Besides, what would be the point?
I can understand why you want Embed to support images from your existing database-application, but it doesn't work like that unfortunately. It can be done, but it would be a custom job to adapt files/Embed to work with your native mysql-application.

Of course, for communities and forums, and even most gallery websites, mysql database is better ... because you want to store logic and features alongside each image. This is not the case for Embed or Files gallery. And even if it was, you can't just cross-mix different applications using the same database to access photos.
Sorry for the long response, but this is only possible by re-coding Files to read the specific database instead. To do that, one would need to study the database ...
