It's a question of the glue which adhering several "emulsions",
photographic layers to the metal surface. :-) For example
the carbon/pigment process which result a pigment tissue usually
which transferable to (nearly) any material. There are a lot of
other type of several chromatcolloid processes to make similar
way it.
Another possible method the burning in enamel photography (on metal,
similar to photoceramic processes).
And a possible special way the using photomechanical or other
printing processes which are using metal plates (ie. copper, zinc,
etc.). The result of these processes usually a print on paper, but
you can use the metal printing tool which has the photographic picture
on the surface. (Mechanically and/or from paint). Examples:
Photogravure, Zinkography, etc.
There are more creative ways also: these are only my first ideas...

PS: Ready silver-bromide emulsions (spray, liquid, etc form) are
available (ie: Liquid Light) also but these are unsportmanslike
tools :-)
