Hi Rabin,
The easy way is a to use a HoverBox. This isn’t really a Wix Code issue, so you can contact the Wix support team . They’ll be able to provide better help regarding the HoverBox.
A more flexible, but more complicated way is to do it yourself using the $w.Image MouseIn and MouseOut functions. This will require coding, and you’ll need a good understanding of the various functions and properties of the $w.Image component.
Good luck,
Yisrael
