Ok, I looked at your source code and here’s what I noticed…
There’s this script
<nav id="nav-arrows" class="nav-arrows"><span id="nav-arrow-prev">Previous</span><span id="nav-arrow-next">Next</span></nav><script>jQuery( '#nav-arrow-prev' ).click( function() { jQuery.vegas('previous'); });jQuery( '#nav-arrow-next' ).click( function() { jQuery.vegas('next'); });</script><script>
jQuery( function() {
jQuery.vegas('slideshow', {
delay:500,
backgrounds:[
{ src:'https://testing.mattgrossdesign.com/wordpress/wp-content/uploads/2013/08/biomedical-front-page.jpg', fade:500 },{ src:'https://testing.mattgrossdesign.com/wordpress/wp-content/uploads/2013/08/Organs-White.jpg', fade:500 },{ src:'https://testing.mattgrossdesign.com/wordpress/wp-content/uploads/2013/08/scotiaband-front-page.jpg', fade:500 },{ src:'https://testing.mattgrossdesign.com/wordpress/wp-content/uploads/2013/08/windmill-front-page.jpg', fade:500 },{ src:'https://testing.mattgrossdesign.com/wordpress/wp-content/uploads/2013/08/Zagato.jpg', fade:500 }, ]
})('overlay', {
src:''
})
});
</script>
Which is awesome. That’s how it should be, but farther down near your footer there’s this
<script>
jQuery( function() {
jQuery.vegas('slideshow', {
delay:500,
backgrounds:[
{ src:'', fade:500 }, ]
})('overlay', {
src:''
})
});
</script>
Now I’m not sure why that’s there but I’m almost 100% positive that’s what’s causing your issue. Let me know if you need further assistance!
