Advertising on Fotopic

Adverts have started appearing on the gallery homepages of those using the free Fotopic service, which gives 250Mb of space of photos, which is fair enough in my book. I've had to slightly alter the layout of my gallery's front page as a result of the new advert box, but it essentially remains the same. I'm slightly concerned that the Google adverts now appearing on my gallery front page all seem to be connected with Fireworks and pyrotechnics. I'm not entirely sure what this has to do with the vast majority of photos I have online. I'll have to see if it changes to anything more relevant given a bit of time.
