* UX: Remove background image after image has loaded
If an image has a `smallUpload`, that may be set as the `background-image` on the `img` element, and the `img` element set to use `lazy` loading. When the browser decides to load the `src` of the image element, it is rendered on top of the existing background image.
However, if the image proper has a transparent background, the background image may be partially visible through the transparent portions of the image.
This change creates an `onload` event that removes the background image when the image proper has completed loading.
