Hi, Thanks for great plugin. I have a scenario, where I don't want to check for all images on page load, but once user reach the end of the image array, I want to update array with another 20 images. Currently it shows error below, once I update the array of images. Any help is appreciated. Thanks

Hey @bachras , new version (4.1) should resolve this. Note that you need to push your images on the fore-last item and not the last one, since the plugin automatically preloads the next image from the current one to have a nice smooth scrolling.
