CSS changes – Main page slider making image fit the full area available?

Hi,

I have an issue with the slider on my site, when uploading the image, they are stuck on the right-hand side and don’t seem to be either centered or filling the slider area?

not sure if this is an issue with CSS/ Theme or just my file is too small or something else?
