I'm having trouble getting images to display when hovering over text. Can anyone offer suggestions on what might be causing this issue? The images are being downloaded when clicked, so I know they're in the correct path. I've checked for common typos and errors online, but couldn't find anything useful. I've gone through it multiple times and even used a linter, but still can't pinpoint the problem.
Any help would be appreciated. Thank you in advance.

$('<img />').attr('src', $(this).attr('data-hover'));
