Save Website as Image Autor: igorlogius

SYNOPSIS
Adds a toolbar button that when clicked will take a full capture of the current website
if possible as one JPEG. If the size of the generated image exceeds the browsers internal canvas limit
the addon will instead save the website as a series of images inside a zip archive (aka. comic book zip-archive )
