Use Storyline Characters in Presenter/Engage/Quizmaker

I have both Storyline and the Articulate Suite and just received the character pack.

While I will be developing a lot in Storyline, I'm getting requests to use the character images in Articulate since not every training piece can be ported to Storyline (some facilitators want to be able to edit their slides).

Is there a way I can use the images in both programs? I thought when I got the images, they would just be pngs that could be inserted into Storyline or any other program but I had to install them into SL and cannot find the folder on my hard drive where they live.

Thanks!
