Hereby a screenshot from my mobile device.
Unfortunately the lightbox is still not working properly.

On a very small computer screen all goes well but on my mobile phone the lightbox is still too big and the quality of the image is still very poor.
(it looks like it downsized the quality to 30% to save some in kbs but I rather have a little longer loading time then poor quality)
On a computer screen quality is good.

Thank you for your response

What browser do you use? We have checked it in Safari on iPhone and Google Chrome on Android and the lightbox looks normal (like on a small browser's window on a laptop).

PS: Try to clean browser's cache.

PPS: The video with "ARI Image Slider" is here. We see only loading icon which is shown by site template.
