Custompress and Image Slider Galleries

I am working on my first project with CustomPress and it is great for what I am doing. I have a question and admittedly it does not have directly to do with CustomPress, but I will be creating a custom field with CustomPress to make this work I believe.

I want each post of the new custom-post-type I am creating to display an image slider of images added to the custom post. I want to use a template tag to display it (not shortcode). I can't seem to find the right plugin that will display the images attached to a custom-post-type and display just those images in a slider at the end of the post. My concept is that each post under my custom-post-type will have it's own image slider gallery.

Any ideas? Thanks in advance for your help.
