Need help getting Lazyload to work on display image when using second image in Fancybox

#1

I have everything working the way I want, except Lazyloading. I have a few small images on the page and I am using Fancybox (Lightbox) to open a different image. https://mrpitbull.com/dog-anxiety.html Thanks for the help.
