Server not showing images and styling

Hello, I used your template and it worked fine locally. However, when I uploaded to HostGator, it does not show the images or styling. I opened a ticket with them and they said it is not a server problem, but a coding problem. They asked me to ask a developer to solve the issue. I am self-taught but still pretty ignorant. Is there something I am missing? I simply edited the code and images in visual studio code, zipped the folder, uploaded to hostgator, detached the file to the public.html folder. Should I run through something before? I did not use XAMPP or anything. Any guidance can help me. Thank you. I uploaded a picture of how it works on my local computer's browser.

The problem was in HostGator, I reuploaded everything via FTP and it worked. You can close the ticket. Thank you
