Adding image sizes to image

When I add an image attribute to the page I noticed that inside of the component the image has attributes to it. When I call my images into the asset manager I do it like the following: However, the height and width aren't available when the image gets added to the canvas. I've tried to get the sizes by doing: component.views[0].el.height and adding it to the object, but every time I try I get 0 because the image isn't available in the DOM yet, so it doesn't know what size it is. Is there a way to pass these heights and widths to the image, I need this for some lazy load functions I'm doing....
