Hi! I want to create a gallery that follows this format:
Also, it is possible to make it with hoverboxes instead of images?
Thanks in advance.
Read Wix Support own pages about gallery and Wix Pro Gallery which would both give you the slide feature that you are looking for.

You can also populate a normal wix gallery with images from a dataset.
If you want to add more effects then you will have to look at adding event handlers like onMouseIn and onMouseOut or by adding html, css and js into your page as Wix won’t be able to do everything.

Also, if you are wanting hoverboxes, then Wix do those too, however you will only get the two images in each hoverbox and you would probably be better off simply using onMouse for switching between the two pics anyway.
