In a typical 2 column layout with a sidebar and a main column that contains a typical image banner in the hero unit area(lets say, 870px x 250px), at what breakpoint do you start hiding the banner image? I don’t like displaying banner images on mobile phones and kindle portrait mode.
I don’t like to hide anything. If I don’t want it on mobile, I don’t want it on desktop. To quote from Twitter:
“Mobile users want to see our menu, hours, and delivery number. Desktop users definitely want this 1mb png of someone smiling at a salad.”
Anyhow, if you aren’t going to show something to mobile users, please don’t make them download it anyway. Make sure the banner image is a bg image, and only ask larger devices to download it (via @media).
