Not sure if this is the right place, though it would have helped me
understand how to use Chained actions more easily as I forget to refer
to the Advent Calendar.

From within MyApp::Controller::Artist::Images uri_for($id, 'show')
gives http://localhost/artist/images/*/show which does not take into
account the artist id so do I have to build uri_for('/artist',
$artist_id, 'images', $id, 'show') which appears cumbersome.
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]);
You can read more about uri_for in the calendar article:

Thanks,
Thought I'd missed something obvious.

+=head2 Referring to the uri
+
+Generating and using URI's from anywhere within your app can be made
+easier by adding the following two routines to your main application
+class (e.g. MyApp.pm).
+
+ sub action_uri {
+ my ($c, $controller, $action, @params) = @_;
+ return $c->uri_for($c->controller($controller)->action_for($action), @params);
+ }
+
+ sub redirect_to_action {
+ my ($c, $controller, $action, @params) [EMAIL PROTECTED];
+ $c->response->redirect($c->uri_for($c->controller($controller)->action_for($action), @params));
+ $c->detach;
+ }
+
+A URI can be used from anywhere within your application using the
+following snippets
+
+ $c->redirect_to_action('Greeting','world', [23, 12]);
+
+ my $uri = $c->action_for('Foo::Bar','baz', [5]);
+
+And just as easily from any Template
+
+ <a href="[% c.action_uri('Greeting','world', [23, 12]) %]">Hello!</a>
+
+ <a href="[% c.action_uri('Foo::Bar','baz', [5]) %]">BAZ!</a>
+
+
Here's a more detailed specification of the attributes belonging to
C<:Chained>:
