Background Photos not Displayed

My front page includes background images in containers with titles and call to action buttons. When I view the site on the phone, the images are not there. The only photos are in galleries that are displaying the products. Does this mean I have to make a separate front page for the mobile version?

Also, I have info boxes with icons. They are fine on the desktop version but on the mobile site they are huge. There are some on the front page and there are cart buttons on the other pages next to the products. It looks awful. I don’t see a way to change the size so that it looks good in both places.

Any ideas, short of having two separate sites? I know I could have a custom front page for the mobile version, but that doesn’t help with the product pages.
