Hello,
it doesnt makes sense to show the images on mobile phones.
But you can chnage it if you want:
Open the file
css/joomlaplates.css and look for this line and remove the:
background-image:none syntax
@media screen and (max-width: 1024px) {
#top-a, #top-b, #top-c, #top-d, #top-e,#top-f,#bottom-a, #bottom-b, #bottom-c, #bottom-d, #bottom-e, #bottom-f,body {background-attachment: scroll !important; background-position: cover; background-image:none !important }
.full-wrapper .uk-container {padding:0 10px !important; width:auto !important}
#menu-outer .uk-container {padding:0!important}
}
