Stacked gallery adds empty space

Hi,
I added a custom code along with files to my website a while ago. It works when I'm using two images in stack mode on top of each other and it creates a before and after wipe. I had no issues with it until I updated the page and now the second stacked image takes all the empty space on my page.  The only way to remove the empty space is to remove the second image but that would get rid of the before and after wipe.

Any suggestions?

Anyone?

Thank you. I got an updated code and resolved the issue.
