Importing Lottie (bodymovin from AE), with bitmap images

I've created some Lottie banner animations in AE (bodymovin) and can bring them into Adobe Dreamweaver. I can see the vector animation just fine. but I can't see the included bitmap .png files.
I can see the .png content when I load the .json on the lottie test site, but I can't see it in Dreamweaver.
I've tried different combinations of exporting the .png images in the .json file and having them in a separate folder but can't get it working.
Any ideas?
Thanks
