Banners and text as well, my margins are already tight enough, so I feel it's important to change out old selling material with promo images and text that targets the new sponsor, and adapts to the content and keywords.

So it's hours of hand labor for now.

I consider using openx, and probably should - but I cant trust doing EVERYTHING in it, so I'm doing a bunch of stuff by hand this week.

What I fear is that the sponsors I am switching to will also fail, or get oversold, etc.
