How do I return the name of an image without the path or suffix?

I have a page attribute declared allowing the user to specify a 'Featured Image'. I wish to use the name of the image in a navigation template.

I'm using the following tag:

<perch:pages id="pageImage"/>

Currently returns the image and the full path, filename and suffix:

/perch/resources/image-name.jpg

What I would like is:

image-name

No path, no suffix.

Is this possible?
