Button to Save Image or PDF on Server Side
Feature to save Image/PDF on Server Side (like the feature to save it on client side). This would ease in building email functionality. If highcharts can save the generated pdf on a server by means of a button click, we can write an email client to pick that up and send as an attachment. Using phantom and options.js on server side isn't optimal sometimes.
De do have an API option on the export server, async, that in effect saves the image for a limited time on our server. Then your script can pick it up from there.
