Disabling Lightbox in Summary Box but keeping links when present

As a test I created a gallery called test gallery. 

Then I gave some of the items in the gallery links 

I created a summary block on another page that uses the gallery as the source of its images. 

Then I created a css rule to kill pointer events for any summary items whose link is from the original gallery (begins with /test-gallery).

It works as expected. Items with no clickthrough url have a standard cursor and are not clickable but those with a clickthrough work properly. 

Here is the code - insert it at the bottom of your custom css area after any other code that may already be there. You'll need to tweak href ^= "***" to reflect your gallery slug 

.summary-item a[href^="/test-gallery"] {
    pointer-events: none;
}
