Use Image as a button?


i want to use an image as a button.
I’ve designed all my buttons in png but impossible
to put as button.
I’m working with mouseup and down, ok on safari but not in iOS.

<div ng-click="take()" ng-mouseup="cameraClass='camera-up'" ng-mousedown="cameraClass='camera-down'" class="camera-up" ng-class="cameraClass" style="position:fixed;top:25%;left:4%;width:120px"></div>

there is no mouse on touch devices)))
use ng-class to change button class according to action you want

ok i’m working with ionic and i’ve found touch events
