Dear all, if you've time when linking to a photo, it'd be great if it was clicky - images on mobile are a bit too small for my tired old eyes.
Here's how I do it (hopefully it'll work here!)

I think the text displays only on hover; one image is the page's whilst the other is the one opened by clicking.
Have a play, please let me know what you find.
