This answers assumes that you are retrieving images from a database in another app (because you'd already now how to retrieve images from a database that you created).
If the database is within another application, you must use a content provider. This link will redirect you to the official documentation. It covers all you will need to know about content providers.
In the most basic terms ever, to use a content provider you must first ask permission. Then you query the application that stores the database rather than the database itself (note: the application you query in turn queries the database). Therefore, you must have documentation that will provide predefined methods that must be used.

Not sure what really you want.
But if you finding a simple way to store image to database, you can try base64 image, it is like a string so simple store and read it in/from database.
To display base64 image on html, use can you
<img src="data:image/gif;base64,base64_data_here"/>
