Halloween 2007 Pictures are missing...

I have no idea why I am missing pictures for the entire month of October 2007 on my computer. I know that I had them at some point. I even remember using a couple on my blog in the past. So, I didn't forget to include a 2007 picture in yesterday's post. I can't find one. :( Does anyone else have a copy of a picture of my kids on Halloween last year?

Help!!
