Is it possible to add a subtle glitch to an image on my site?

Hello, I was wondering if it is possible to add a very subtle 'glitch' animation to a black and white photo? Similar to the image on the site here: https://www.shabaniddrisu.com/

I have tried to search online but can't find anything as subtle/randomised

Many thanks,

Best,

It is a whole lot css/html coding. Just to give you an idea of how much it takes to make something move look here:

Sure no problem, many thanks!

I appreciate your input.
