Re: Background image

Hey guys, I am new to wordpress and its themes. I build my site using the Catch Responsive Pro. I really like this theme but I am having a issue I can not figure out how to fix. My background image use to look good on all my browser but now I notice that my background image is getting cut off. Can someone tell me what I have to do to fix this and make sure that I will work for all screen size? my website is: www.signgalaxyinc.com in case you need to see what I am talking about. Thank you!
