Shawn I have figured out why that head won't work.
My app was checking for images with a height less than 560 and the head height was 560.
I have corrected this and made it less picky, it can be 5 pixels under or over.
And as for the string not being converted to boolean, I have fixed that and have attached a image of the actual error it's self.
Anywho I have released v2.2 which includes a beta of the walk being added.
Note it isn't done yet, so please don't post like "it's not working properly" Thanks
