Image that follows scroll down.

I'm sorry if this is not the place to ask this. I didn't know many other places.

I want to write some stuff on a page (I don't really mind where, could be on Google Docs if its possible there) and have an image, on the right side of the page, follow the screen as the reader is scrolling down, so they can look at the image while they read the text.

I want to know if you all know any *simple* way to do this (like a website that would let me do it, a program that would let me write an article with a functionality like that).

If not, I wanted to know if you all think this could be done in html/css/js (I know a bit about all 3, but I'm not great at either), and if so, if there are any sites that would let me play with that idea without having to create the whole web page/ host the site on my own.

P.S.: I don't really need anyone to explain to me how to do these things in HTML, I can learn on my own, I'd just like to know if its feasible or if it'd be too hard and I should give it up
