Hm. Are you sure it's getting passed a filename? What exactly is in the page.featured_image variable?

I thought JPT would fail more gracefully than this, it's probably worth adding a check for that.

I also ran it through a mime detection program to see if the jpg was corrupt.

Hi,

I am using the tag with {% picture "{{ page.featured_image }}" %} which in the blog post is:
featured_image: "/uploads/test.jpg"

And I have the following error undefined method `delete_prefix' for nil:NilClass

Could this be linked ?
