Picture of the Day wallpaper - Can't read Shortcuts text

When I have Picture of the Day enabled, the text labels for the Shortcuts is unreadable if the picture's colour clashes with the text colour. The text labels should have a bubble of contrasting background, perhaps with 50% opacity (like the icons do, and like the widgets below do).

I've attached a screenshot. I had to blur out the shortcuts that are over the trees in the image, which is unfortunate because they were the worst ones to read. The one over the roof tiles is hard to read though. Even the Firefox logo text is partly over some tree foliage and the low contrast is an issue there too.
