I cannot get the hyperlinks to work on my updated pages

Ok...I'm rebuilding my website, and on my bookcover.html page the hyperlinks to the books listed will NOT work regardless of how many times I redo the d*** page and upload it to my server. The new page will NOT reflect the changes. Also, on my gallery page, two new images will NOT load at all. Same problem. They won't update. This is royally pi**ing me off, and I don't know what to do about it.
