Clickable Tour Icons: Production Quick Fix

Found that on production only, clicking on the icon for the tour only works if an image tile was not generated for the tour and we have the default chevron icon. If we have an image tile, it is no longer clickable. This is likely because the underlying default image, which had the click event, was replaced with a new tile image. We only have generated tiles in production, which is why this didn't show in development/test. Changed clickable item from the image to the image containing div which should resolve.

Since this is changing a single link reference, and the tour is still runable from the main link, please can this quick fix to go in this week in advance of Monday's demos? Thanks!
