This page is pretty strange. And it has a number of issues, I’m afraid.
The one you’ve noticed is because one transparent container “myExtraContent3” is overlapping the whole page. It absorbs all the clicks and doesn’t let any of the clicks fall through to the links underneath.
You can see in the screenshot I took below. The green is your main image. It is correctly linked. But aside from a tiny bit that is visible on the far right side, you can’t click it because the pink covers the whole thing.

I should also note that I see a few other strange issues with the page too.
One is that your links contain " " (space" characters. While most browsers are OK with that, it’s definitely not valid code and is highly discouraged. Usually RW takes care of that kind of thing for you during publish – I’m not sure how you got those sneaked under the wire. 
This page loads over 20 css files, 7 javascript, and… 5 fonts OMG 
The page is also a stacks page – but its – well – it’s unrecognizable as one – it seems to be missing some bits somehow.
I’m honestly not sure how you did this. Either there is some interesting JS re-organizing the page on the fly (what i suspect), you’ve dismantled and reassembled the page by hand, or … well… or you’ve found some pretty strange bug in Stacks (i hope not). 
For all of these problems I’d recommend the same thing: simplify simplify simplify.
This page is not too terribly complicated – but the code/scripts/fonts/structure is REALLY complicated.
I suspect you’ve got some pretty custom setups, a very adventurous theme wizard, and/or pluskit/extra-content/i-don’t-know-what that seem to be working at cross-purposes.
I might try re-building the page using just basic tools. Toss ALL the extra bits out for the time being. Try to build the page with just the basic built in stacks.
Then, slowly, one by one – addd back in the extra bits you absolutely NEED. And realize that each one will slow the page down – and slow pages are unread pages on the internet.
And if you discover it breaks again while adding things back, then… well… take a step back.
Good luck,
