Squeezing slides with Meteor slide plugin

Hi,

[ Moderator note: link fixed, careful posting links here. ]

I have webiste https://www.btrade24.com/ and I am using Meteor Slides plugin for the slide show on the homepage. On a bigger screens (resolution 1920×1080) slides show normaly, but on smaller resolutions like on laptop (1366×786) slides are squeezed and I don’t want that. I want slides to be center positioned and in normal size on all screen resolution.

Can someone help me with this?

Thanks a lot
