From the documentation of uri_for (perldoc Catalyst): 
$c->uri_for( $path, @args?, \%query_values? )

If the first element of @args is an arrayref it is treated as a list of 
captures to be passed to "uri_for_action"

I would do: 
$c->uri_for( $c->controller('Artist::Images').action_for('show') , 
[$artist_id, $image_id]);

this can be shortened by writing an action_uri sub in MyApp.pm: 
$c->action_uri( qw/Artist::Images show/, [$artist_id, $image_id]);
