Title: Remove unnecessary URL encoding when setting bg image

this.imageSrc is not being set as URI component so this encoding just breaks URLs containing "/" and other common chars. The only URL char you'd would worry about would be `)` but that's a) extremely rare in an image URL, and b) would probably be URL encoded by the browser when it read the property.
