There are many reasons why the website might load longer than usual. Here are few of them:
– hosting speed
– the size of images (uncompressed, high resolution)
– a number of images on the page
– internet speed (local problem)
You might need to turn off the preload of images, which we’ve added by default. That way you significantly shorten the time of loading. Simply add noPreload class on the <body> element https://designmodo.com/slides/app/manual/#preloading
