Where are the codes for this auto-play function on the product page

[Qing1]

Hi

I use old Debut theme. Today I copied the dawn theme the code file theme-editor.js to my Debut Asset.

Then a miracle came. When I clicked the product photo on my home page, the product page started to run the all the product variant photos and put all of them on the  top of the product page. I don't know if I need this function. I deleted the theme-editor.js, thinking by this way I can remove this miracle. But I cannot succeed. Can anyone help me to delete this function?

Solved. Thanks.
