Change Play Store Logo / Remove the "Download @ Google Play"

First off, I have to say, what a fantastic Plugin. We run an Android site so being able to easily and quickly link to the Play Store is huge.

I had just 2 questions that are very similar. Is it possible to change the grey Play Store logo int he background of the link to the Play Store, and also if the image can be switched, how would I go about removing the “Download @ Google Play” that is above the image.

Thanks in advance, and again superb Plugin!
