Image Won't Replace

I'm working to replace the image in my EPUB so IngramSpark will accept it, but I can't figure out how to get it to actually replace. I deleted the old image, it shows up nowhere in the code anymore, then added the new image. But everytime I load the new EPUB, it shows the old file's name with the "image logo" and no image, and the new image does not appear anywhere.

I've checked the code and replaced it a few times directly with the editor as the guide says, but nothing is changing when I load the new EPUB.
