Gone from Google

For some reason, some of my websites are not listed on Google anymore.

One of the websites was just a fun website where I had a bunch of pictures I took at a local event. A few weeks after I posted the webpages, a few of my images were listed among the first ten images when you searched for that particular event. I put a picture of my friend on one of those pages. When you googled his name, that picture came up first. Now I get nothing of mine when I do an image search. The webpages themselves which used to be ranked around 50th, don't come up at all.

Another lost page was a main domain page. I had a bunch of wordpress blogs on subdomains. The main page was just a space filler with a photo of something unrelated to any of the subdomains. When you did a google image search for that item, it came up second or third. And I wasn't even doing any SEO for that page. Now the image doesn't come up at all when you search.

These pages had adsense ads on them but they weren't selling anything. I wasn't backlinking to them and wasn't doing anything, blackhat or otherwise, to try to get them ranked. Suddenly they aren't on google at all anymore. Is this just some weird Google dance? Or are they out to get me.
