No images exported - website publish issue - or doing something wrong?

I've imported images into my project. These image display perfectly when previewing the site.

Problem is that when I exported my design, none of the images got exported.

Looking in the images folder, I could see that the image files did not exist in the exported site folder.

The only image that was showing on the published site was a phone image from the default landing page theme.

I ended up copying and pasting all my images into the "assets\img" folder - which is where the phone image was exported to.

Now that I manually placed my images in that folder, they can be found and thus show on the published website.
