You could use gdk_pixdata_from_pixbuf(), gdk_pixdata_serialize() to
store the image on the database server as a BLOB or converted to a
string encoded in Base64. 
And use gdk_pixdata_deserialize(), gdk_pixbuf_from_pixdata() to convert
the data back to a GdkPixbuf for display.

See

But, IMHO, storing image in a database is not the best way: 
storing in database the path to an image stored on a filesystem could be
a better idea (on a single computer, the application will benefit from
the filesystem cache).
