WordPress site moved to new wordpress site – images not loading

I have been using one wordpress website to create a test site (https://www.heatherpeberdy.com) as it is finalised, I have exported and imported it to the new site (https://66.147.244.80/~oceania2/).

All seems to be working correctly, except for the following:

Images – where I have used a “shortcode” from the “Striking” theme to include a thumbnail image, the image is not loading. However, for the images that are linked to a lightbox, when clicked and the lightbox loads, the images can been seen in the lightbox.

Can someone please help me to resolve this issue.
