First-timer hit a snag Options

[esfres34]

I have no real web design experience but I offered to help get an artist friend online, thinking that I could use a premade template and cobble something passable together. It looks ok but when I uploaded it to amazon web services to host it, most of the image went dead (except for 3) and I don't have the knowledge to understand why. I'm hoping someone here can give me a clue as to what's happening.

Here's what the page looks like offline. image 1

But here it is online. image 2

It's puzzling to me why 3 of the images out of ~60 work but the others don't.

I thought it might be something to do with the image size not fitting in the thumbnail space but here's another great big image that is working. image 3

Here's the snippet of code. image 4

The template I'm using is called Strata.

I also uploaded to githubpages and the same thing happens. I really have no clue what I'm doing or why it works offline but not online. I reuploaded multiple times and it's always the same.

The only thing I changed with the template was the original went like "img src = images/thumbs/imagetitle.jpg" and there was a seperate folder for thumbnails, but I changed it to "images/fulls/imagetitle.jpg" to just point to the full size image. I went back and created a smaller thumbnail image and pointed back to "images/thumbs/imagetitle.jpg" but it didn't fix it. I don't really know what the "class="image fit thumb"" bit means.

Does anyone know what might be happening?
