Ah, I see
Ok all we have to do is similar to the image view.
We add a rect and hide it. This will be the caption box.
Then in the JS I have added an Array (like object) i.e key valued pairs {Name : value}
The names will be the id of the thumbnails and the values will be the captions.
We then just show and hide the caption box when needed and change it’s innerHTML also when needed.
We change the innerHTML by getting the matching thumbnail name in the array which will return the value caption
