mysterious slider image inserted

Hi guys,

One of the pages on my site has somehow mysteriously got a slider image (or set of images) on it..

It doesn’t seem to show up in the text html – there is no slider images in the gallery of that page – I really have no idea where it came from, and how I can get rid of it (quickly!)

I don’t really know code, just grateful for all the help this forum has given me.
site is:

Thank you
