By way of example, consider this site configuration:
{{< code-toggle file=hugo >}}
baseURL = 'https://example.org/docs/'
{{< /code-toggle >}}
And this template:
```go-html-template
{{ with resources.Get "images/a.jpg" }}
{{ with resources.Copy "foo/bar/b.jpg" . }}
{{ .Key }} → foo/bar/b.jpg
{{ .Name }} → images/a.jpg
{{ .Title }} → images/a.jpg
{{ .RelPermalink }} → /docs/foo/bar/b.jpg
{{ end }}
{{ end }}
```
We used the [`resources.Copy`] function to change the publishing path. The `Key` method returns the updated path, but note that it is different than the value returned by [`RelPermalink`]. The `RelPermalink` value includes the subdirectory segment of the `baseURL` in the site configuration.
The `Key` method is useful if you need to get the resource's publishing path without publishing the resource. Unlike the `Permalink`, `RelPermalink`, or `Publish` methods, calling `Key` will not publish the resource.
