Help with centering images in Revolution Slider

[tg_nyc]

Hi all, I'm new to the Forum. I just finished building my online portfolio site: http://tonygamino.com and while my images look centered on a smaller screen like a laptop but when I look at my portfolio on a desktop all of my images move to the left and are not centered. I'm wondering if anyone here might be able to take a look and understand why this is happening and what I can do about it? I built my site with a theme called Professional Resume/Portfolio Theme created by TheThemeLab and purchased from GraphicRiver. Thank you in advance!

Not sure which images you are writing about as everything looked OK to me on laptop screen 1600 x 900. Could you be more specific for me.

Rick, thank you for replying. Yes the images look centered when I'm on my 15" MacBook but on my 27" screen at work they are shifted left and not centered.
