How to run custom function by hovering or clicking on cell in google spreadsheet?

I need help to make a table which will have a cells as product thumbnails and by hovering or clicking on this small image, I want to show the pop up with big image of product.

(Right now it works as hyperlink, but it is not enough)

I know we have a few ways how to run function right now:

from a custom spreadsheet function
from a trigger (from spreadsheet like on open, on edit or on form submit, or Time driven)
from a custom menu (which must be created by e.g. on open)
from a custom user interface (which must be created by e.g. on open)
from a drawing or chart
from the script editor

Is there any way how we can trigger event like hover or click on cell in table?

I have a few ideas right now :

Some how place big image in comment or note in cell.
Make a custom function which will return image/chart/drawing as a value and apply function for this image/chart/drawing. But seems we should have much more easy way to do it =)

I know this is a similar question as: This and This but they are old and google has made an API update since December 11, 2014.
