Are you asking how to make the tooltip itself bigger when you hover over a Tippy link? There are two ways to do this:
You can modify the stylesheet and change the size specified under .tippy_tip which will apply the change to all your tooltips.
You can also specify the size on a per-tooltip basis. For instance:
[tippy title="Check out this image" height="500" width="300"]<img src="myimg.jpg" />[/tippy]
The values are in pixels, so that would create a tooltip 500px X 300px.
Are you asking how to change where the tooltip appears when using it with an image? In the Tippy options page in the WordPress dashboard, look for the “Tooltip Location” section and change it from “Tooltip positioned under the Tippy link ” to “Tooltip positioned under the mouse pointer”. The first one makes the tooltip appear under the trigger/link – in this case, an image. The second one makes it appear directly under the mouse cursor.
