How to use filename as Title in multiple image node

I have a node with an image filed that allows unlimited images.

I would like to replace the Image/Title field with the filename.

Using [node:original:field_client_images] gets me close but 1) it is the whole path and I just want the actual filename. And, 2) it puts every filename in every Image/Title for the node.

Is it possible to just insert the filename using this module or is there a better approach?

Thanks!
