inside that folder will be a subfolder for the date picker on your page, it will start with the same name as your page, the date picker images including the right arrow are in the images folder under that.
Yes it all seems to be there Jason. I actually set it up firstly on my PC / testing server so no files needed to be uploaded anywhere.
I've also set this up on three pages and they are all the same (image missing (or not showing)).
Strange!
