Picture Formatting Issue

Hey,

I’m having an issue with an image on my site. Whenever I insert my new desired image at the bottom right corner in place of the old one, the image covers the entire front of the box instead of being in the bottom right corner on the homepage. The code for this one is currently

.main_content {
		background: url(images/lach_photo.png) no-repeat bottom right;
                
}

The URL is https://www.lachfinancial.com

Thanks ahead of time!
