Hi dizzy578, and welcome to the forums.
At first glance, I can't see a problem with your code, but I'm very tired, so I might be missing something.
Have you checked the filename is absolutely correct, and is your zip file definitely in the Uploads folder? (That might sound patronising, but it wouldn't be the first time I've saved something to the wrong place and then wondered why things don't work. :rolleyes:) I presume the filepath to Uploads is correct, because otherwise your image wouldn't show.
Have you tested in more than one browser?
[ot]I notice you have the "alt" attribute on your image set to "nonstop". The purpose of alt(ernative) text is to provide information if the image is unavailable for some reason; for example, if the user is visually impaired and using a screen reader, or simply if the image fails to load for some reason. In this case, the image forms a link, so you want that to be functional whether or not the image is displayed. "nonstop" doesn't convey much; "Download Non-stop mp4", or something similar, is much more helpful, because it explains what happens if you activate the link.
