An issue on my portfilio site

After I finished my portfolio project on freeCodeCamp projects. I upload my project in github and open my site in different browsers and devices.
I have a big issue with my pictures on the project.

=> When I open my project site in fireFox browser I did not see any problem

=> When I opened the site it self on safari browser I found the issue:

=> Also the same problem in safari browser but on Ipad :

I think this is a issue with the bootstrap probably

When I viewed your site with Chrome and Safari I did not see any issues. Is your Safari browser up to date?

Btw, it would have been better if you had included a link to your GitHub page. Had a hard time getting it from the screenshot.
