A few of my images are not loading on my website [on hold]

I've just recently started hosting a project website that I'm doing for university and a problem that I noticed was that a couple of my images aren't loading. This doesn't really make sense to me considering that the load fine when I just open up the webpage In chrome straight from my desktop. The images that aren't loading are also in the same folder as other images that have loaded correctly which just adds to my confusion. Any help appreciated. Thanks.
