Post Slider with full width and less space between images

Hello,
I like to use the „Post Slider“ for my blog entries. The style of the slider should be like the „Masonry“. 3 images in a row with max. 15px space between each pic and full width screen. The images should also crop like the „Masonry“ is doing.

Is that possible?

Right now I´m using the „Masonry“ on my HOME site. I want to replace it with the blog post slider.

I´m looking forward for your answer.

Thanks

Karl
