As far as I know there are two ways for storing images into a database: you might either

store the image file content as a binary object (see BLOB at Wikipedia[^]).

or

store just the image file path as a string (effectively storing the image file itself in the filesystem).

In both cases you could later retrieve the full binary data of the image file, in order to manipulate it (e.g. showing, processing, ...).
