Changing Duration of Slides for Flexslider using Sparkling WordPress theme

How do I change the length of time that each slide shows for in the slider? I think it is set to 8 seconds per slide and I would like to set it to 5. I know this is probably really easy but I know very little about code and couldn’t find where to change it. Thank you!

My website is jsaphotography.com

Now it is set to 7 second but you can change it by adjusting this value

slideshowSpeed: 7000, //Integer: Set the speed of the slideshow cycling, in milliseconds

In flexslider-custom.js file that you can find on:

sparkling/inc/js/flexslider-custom.js
