Hi @maxi394
the website you showed uses the Fullscreen Slider.
When you inspect the code, you can see that the text is aligned on the bottom left with position absolute:

This could be done with Custom CSS…
But also I think the "double-images" are one big images which is set as a background of the whole row.
