A background image can be made translucent by changing the opacity. A problem that arises by doing so is, that any element placed upon that background, will inherit the opacity, and text will more or less disappear into the background and be hard to read. The solution to this is to place another container on top of the first one, and give it a transparent background, and and then pop the text on top of the new container. That solves the problem, and it works as far back as in IE9.
