Google Ads has become a non-insignificant contributor to the bottom line here at HeroMachine Central. As of yet I haven't put any ads in the actual apps themselves (the big blank white box in the upper right corner). The only way I can figure out how to place them there means that the ad is still present when you go to "widescreen" mode.
So my question is, how irritating would that be? You'd still be able to output the image in widescreen format without the ad being there, but online it would be present.
