I am really surprised to notice that this so-called fork from Jetpack does not progressively load and scale your images like the real JP Carousel does!
If you open the Developer Tools in Chrome and go to the example at
you can see that only the requested image plus next and previous image is loaded.
For example if there are 9 images and I click on image 5 to open the carousel, only image 5, 4 and 6 are loaded. Clicking on the next arrow will have image 6 already loaded and will now load image 7 etc.
This preload technique is used in any intelligent slideshow / carousel.
"Gallery Carousel Without JetPack" just loads all the images at once!!
Also I uploaded 4608x3456 images to my WP galleries and this plugin just loads all these enormous images in their original size
The real JP Carousel loads scaled versions of your images based on the viewport or screen resolution. For example
will be loaded on a small resolution screen and
when I visit the same page on my HD monitor.
Just on a sidenote, it seems the 'other' plugin "Tiled Galleries Carousel Without Jetpack" does appear to do exactly the same as this one.. Only the REAL JP Carousel features an intelligent preload strategy.
