Make slider thumbnail images links

Hiya

The thumbnail images for the home page slider don't seem to be links. On hover the pointer changes as if the thumbnails are links, but nothing happens when you click on them. The main slider images are links and working correctly, so I have set them in theme options. I don't know if the thumbnails don't link by default, or if they're just not working for me. Is there a way I can them to be working links?

As always, I'd really appreciate your help with this. Thank you.

 

Hello,

Right side carousel image are used to change the slider image.
So it is not possible to link them with the other pages.

 

I did wonder if they only changed the slider image, but they weren't even doing that. However, I've realised that the problem was that I was using a computer that had AdBlock browser extension installed. I disabled it and now the thumbnails are changing the slider image.
Thanks for your help anyway.
