Image hover text link

Hello,

I’m trying to get image hover text link.

EXample:

Text link 1
Text link 2
Text link 3

When moving mouse over text link1, it shows clickable image
over text link 2, shows other clickable image
and so on

I’ve found this amazing CSS script here: https://www.dynamicdrive.com/style/csslibrary/item/css-image-gallery/
But images are always on top, if i scrool page down, i can’t see the images.

Anyone can help?
Thanks
