Upload a data using the url of the item without download it locally.

Hi guys,

As I upload a image by giving only the url of the item like
"http://www.happybirthday-cards.com/wp-content/uploads/2014/09/happy-birthday-pictures-11.jpg".
Where the exact image should be stored in the storage(eg. AWS S3 bucket)
for the future process.

Please give your suggestions/ideas to develop my thing.

The transfer process has to run somewhere -- if you don't want to
run it "locally", run it on a server.

Or frame an actual question, if there's more to this...
