actually there is a new way to do this thats easier.
simply put text on the images using the new settings in the sidebar:
https://laytheme.com/documentation/gridder-elements.html#text-on-image
and use this CSS to make them appear on hover:
html.no-touchevents .lay-text-on-element-overlay{
opacity: 0;
transition: opacity 300ms ease;
}
html.no-touchevents .col:hover .lay-text-on-element-overlay{
opacity: 1;
}
