I have the Version 1.3 of Propulsion which I believe is the latest to this date. My problem is in Chrome with the slideshow of the featured image on a single product. I upload just 1 jpeg and after I publish, it shows 1/2 at the bottom so when you click to open that empty second image, it gives the error "Image cannot be loaded. Make sure the path is correct and image exist"
Now, with firefox is all good, it doesn't bring up that ghost image or anything. So what would be the cause of this evil behavior?
Try to open the image on this product with chrome to see what I mean.
