Image for the ACM ICPC Bootcamp '13

[TheFlash98]

I'm not sure who sent the PR for this, or how this happened but the image for the 2013 event, ACM ICPC Bootcamp is missing/doesn't show when you serve it. It should be a relatively easy issue. Just add the image to the images folder and the image name to the file _events/13-ACMICPCBootCamp13.markdown.

Try adding the image, try doing it yourself.
