/**
|
|
* A component to manage a user profile image. By default it just handles picture uploads,
|
|
* but if passed a bound 'email' property it will render the user's gravatar image
|
|
*
|
|
* Example: {{gh-profile-image email=controllerEmailProperty setImage="controllerActionName"}}
|
|
*
|
|
* @param {int} size The size of the image to render
|
|
* @param {String} email Reference to a bound email object if gravatar image behavior is desired.
|
|
* @param {String} setImage The string name of the action on the controller to be called when an image is added.
|
|
* @property {Boolean} hasUploadedImage Whether or not the user has uploaded an image (whether or not to show the default image/gravatar image)
|
|
* @property {String} defaultImage String containing the background-image css property of the default user profile image
|
|
* @property {String} imageBackground String containing the background-image css property with the gravatar url
