Zooming on hover can be done with CSS. See https://www.w3schools.com/howto/howto_css_zoom_hover.asp
If you don’t want to write your own CSS, you can do this.
The Bootstrap tooltip widget (with context) lets you add a hover. You can set it to render as HTML, using an attribute on your entity that surrounds your image url with an <img> tag.
If this is a Mendix File entity object, you can access the url of the image with the GUID (retrievable using CommunityCommon’s getGUID java action).
