OK, I did it. Put ads on the site. No, I don't like it either, but the effort I put into it needs to pay, so this is the way it will have to be. (If anyone wants to offer me large sums of money to take the ads off again, I'm all ears!)
For me, it looks OK in Firefox and IE10. If anyone has problems let me know in the comments here, telling me which browser and version you are using.
