We need to make a presentation to introduce our courses (content 360 rights issue)

Hello team,

So, we have some great-looking courses that we've created in Storyline. To introduce them to our users we'd like to create a short presentation with images from the course (for example, we'd like to introduce the characters that appear in the course) - I've been asked about rights. From your Terms:

You may use the Content Files to develop your e-learning end product in our Services (“End Product”), including modifying and embedding the Content Files into your End Product, and reproducing and distributing the Content Files if integrated in your End Product. However, you may not use or distribute the Content Files on a stand-alone basis outside of your End Product.

I would take this to mean, I cant use the picture of the character directly in Powerpoint (even if the presentation belongs to the product) - but I could take a screenshot from the course, and use that? (even if I cut it down to only the part of the screen I want for my presentation? )

Can you clarify this for us? 

Thanks

Adam
