Hi @MoritzMoritz
I can quickly explain how I would do it:
List itemDisplay all the images with text next to it as projects
Give the images a class and hide them with display: none;
I would go for jquery to show and hide the images on hover. But I think the CSS way is also possible. So when you go for the CSS you make the images go display: block;on hover of the project.
Don't forget to position the image position: fixed;that it always stays in the same place.
This is already what you did somehow.
Can you show us an example of your tryout?
I know somewhere in this forum this topic came up. Maybe have a search for that as well.
All the best!
