Inline images appear when running locally but do not render when deploying via GitHub pages

I am trying to use the hugo-creative-portfolio-theme to build a site that can be deployed via gh-pages on GitHub. Everything has been working as expected when developing the site locally. However, when I push the site to the gh-pages branch, the inline images in my posts no longer appear.

Here is a link to my about page: new_site/_index.md at main · CurtLH/new_site · GitHub
Here is a link to my published site: Curtis Hampton

Any help in understand why inline images render as expected locally but not when deployed to GitHub pages would be greatly appreciated.

Simple,
Your site is in sub-folder, but image refer to folder in main domain.
