Thanks for the reply!
That was the first thing I tried after thinking that I uploaded a bad image or doc. I sent them there again and cleared the browsers before attempting to load the page again.
I found that some image names in the document had capital letters in the extension part of the file name, that seemed to fix the one set of images from not showing up. But I searched the entire document looking for more of those and didn't find any.
I have not officially started learning HTML yet, but I wish I did. I'm new at this so maybe it's a "newbie" mistake.
