My images run by themselves in my website

On my website (https://3petitscarres.fr/), images rotate by themselves ...
Explanation : the image above of text "sac a vrac" is in a certain rotation and when I hover it the rotation of image change. demonstration of my question

I think it comes from uploading my images. I am transmitting the image data and not the file itself. On the server I recreate images from data.

Do you have answers or leads to solve this problem?

Thanks
