This one also got lost -- I assume do to my single-line patch.
Here it is again with docs and tests.
There's two things: first, I added docs for the existing but
undocumented "root" parameter.
Second, I added a way to specify a separate file and url path when
the path and the url space don't match up.
Here was my original, yet a bit verbose, example:
Under Catalyst applications can (or should) be designed to run
in any URL namespace. That is, Catalyst uses PATH_INFO to determine
the action to take so the application can be aliased anywhere (just
like a plain old CGI script):
With Apache:
Alias /myapp /path/to/real/app
Alias /myapp/also /path/to/real/app
So relative paths won't work.
With that you can't easily use the Image plugin because it builds the
src tag based on the filename.
USE Image(
root = '/path/to/real/app'
name = '/images/foo.png'
);
So, it will find the image, but the src will not include /myapp or
/myapp/also.
So with the patch I can specify the file name and the URL
separately:
file_name = '/trainers/' _ item.id _ '.jpg';
image_file = c.path_to( 'root', file_name);
image_url = c.uri_for( file_name );
USE Image( file = "$image_file", name = "$image_url");
(the quotes are needed to stringify)
The other reason is a url /images/logo.png might get dynamically mapped
to different files based on, say, some value in the session. So need a way
to specify the path and url separately.

+A "root" parameter can be used to specify the location of the image file:

+ [% USE Image(root='/path/to/root', name='images/home.png') %]

You can also provide an alternate name for an Image plugin object.
