I'd start by placing the ones that you do have more prominently on your site. Right now they're below the fold and are the very last thing on the page. However, to me they're far more descriptive of what the product is than a picture showing that you connect a mobile phone to a server. I also want to know why you're different. I can already connect a mobile phone to a server. Why are you better? Also, one thing that confuses the hell out of me is that the picture says "Create and instantly deploy mobile apps" and then later on you have text that says "The end-users (the humans in human.io) use our iOS and Android app". So which is it? Do I create a new app or do they use your app? I think what this may be is mechanical turk for mobile devices. That actually seems pretty cool. In any case, good luck!
