Image missing from polyhole page

[RickSeiden]

The polyhole page is showing an image not found error. I got the gist of the page and I think the image was supposed to be the drill bit picture.

Per search results for "polyhole", it does appear to be the drill bit picture. I am unfamiliar with how storing images works in github wikis, but I'd be happy to create a replacement image for use in SuSi's wiki.
