Reply To: Home Image not resizing

If I remove this from your css it works (line 2439) –

@media only screen and (max-width: 1800px) {
	
	.front-page-1,
	.front-page-4,
	.front-page-5,
	.front-page-7,
	.front-page-9,
	.front-page-12 {
		-webkit-background-size: auto;
		-moz-background-size:    auto;
		background-size: auto; 
	}

}

Then add the background-size: cover; mentioned earlier and it should work. It worked for me when I tested this on your site.

If you still are unable to get it working, let me know. I can login and make the adjustments for you if you want to create a temporary login.
