Hi Matt,
This is weird because the slider works but inconsistently. If you reload the page while you’re already scrolled at the footer/bottom, then you’ll see the images load with the page.
However, the very same slider, page content, and theme options settings, loads the slider constantly on my dev site.
Please do a testing for a plugin conflict. You can do this by deactivating all third-party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Let us know how it goes,
Cheers!
