Can't save PowerPoint as images with automator

I am trying to use automator to create a set of slides from power point for a screensaver. I want the user to be able to drag the power point onto the automator App, generate an image from each slide, and save it to the 'Slideshow' folder and delete the pdf used to make the images. Then it should delete the pdf and images generated and either move the power point file to another folder or delete it. I'm using OS 10.8.4.

Here's what I have so far:

STEP 1: Convert Format of PowerPoint (to pdf)

STEP 2: Render PDF Pages as Images

STEP 3: Move Finder Items (to Slideshow folder)

STEP 4: Find Finder Items (with extension pdf)

STEP 5: Move Finder Items to Trash

When I run a test I get a green checkmark on all the steps, but this workflow does absolutely nothing. At one point I tried saving the photos in iPhoto but that didn't work either. What should I do to make this work?

Thanks.
