Trouble adding images

Hi,

I am not sure what I am doing wrong but I can't seem to get images to be embedded in my compiled epub. Here is a link to a folder with the relevant files: http://bit.ly/15NESS8 if they help or are needed. Any help would be appreciated. I did notice that in the epub.rb document images seem to be included in the target but I wasn't sure how to debug my problem with this. Thanks!
