Sometimes people just store the path to the picture in the database.
If you want to store the picture itself, you can use column type BLOB. How you work with BLOB can depend on your DBMS and any support you're getting from frameworks you may be using (Hibernate makes it easy). With raw JDBC, you can insert a row using a PreparedStatement and its setBinaryStream method (or setBytes, but I haven't tried that). In the other direction, to get the data out of a ResultSet, you can use getBinaryStream (or getBytes, but I haven't tried that either), or getBlob and Blob methods.
