Get rid of the white border padding and loading icon

Hi everyone,

This plugin could be perfect if would be faster in loading the images when you navigate them. But it’s not at the moment.

I would love to get rid of something, maybe I need to add a css, but I don’t know how:

1. I do not like the white border around the image: https://prnt.sc/2JtemCsJN7rl so in consequence I don’t need of: play slideshow. I don’t want the users use it even, and I would love moving the close button on the top possibly right outside the image, close to it not way far, but outside the image. Is it possible?
2. The loading icon when you mve from an image to another is horrible to see, better don’t have it, especially if you find a way to load faster the images.
3. I want to disable the zoom images on mobile.
