Using a image to a "back to top button" in the footer

Site URL: https://willlai.com/

I just used the anchor link to relieve back to top. But I got a problem from different page:( 

Hope someone can help me. Thanks

Hi. What problem? Can you explain in more detail?

You can check my website. I have a arrow sign image at the footer. Can I use it as a back-to-top button?

you could just make the link #header

This would take you back to the top of the page.

change image url to #top

If I want to tap it and scroll to the top smoothly, how can I do
