Wp Photonav starts with no image

Hello! I’ve been having problems with this plugin, and I think it only happens on Google Chrome. I have a panoramic image that is not 360, and I want it to start rotating from the left until the image ends. However, for some reason, the first time I see it in Chrome it does the exact opposite, starting off with no image and this one sliding in from the right. It’s weird that it doesn’t do it anymore when I hit reload, unless I hit Ctrl+F5. Has this happened to anyone? Is there something I’m doing wrong in the shortcode?
