Hey Sculley,
you’re absolutely right, it’s 950px instead of 960px – thank you for the correction. Still, regarding your situation:
– please make sure that you are uploading the images into the slides in the “Header Slider” tab of the Theme Options panel, and that you hit the “Save All Changes” in the top right after you upload the image.
– if you are using any sort of caching plugin (e.g. W3 Total Cache or the like), please deactivate it while the website is in development, and hard-refresh your browser.
Please let me know if none of the above helps resolve the problem!
Sincerely,
Andrii / Satori Studio
