Can I add two slides in center and two on corners?

[sheetal-mandyal]

Hello,
I am using iosslider in my wordpress theme and I want the slider to show two main slides in center two others on the corners, right now I have modified the css and the slider is coming up like this-

It's showing three images, but I want it to come up like the image below-

So how should I proceed for this? And can I use lazy loading in this slider also?

Thank you!!
