Thanks Ziggy - I'll see if I can get it working now I know I was clicking in the wrong section to add code!

Many thanks for the suggestion Ziggy - I'll give that a try 🙂

You can try adding a pseudo element using CSS, a bit like this:
.collection-type-gallery #thumbnails:before { content:'text goes here'; display:block; font-size:2rem; color:#000; }
