get_picture | 一款可以爬取图片、压缩图片的小工具

I try to write a component which renders a picture fetched from a REST-Server. I have to fetch the picture on the server-side because I don't want to expose the REST-Server to the Internet. Because of this, i can't simply put an "img" tag in the html. (The REST-Server runs on the same system as the Meteor-Server).

Lets say, the Meteor-Method "get_picure" fetches the picture from the REST-Server and returns it to the component. The returned object is the plain result from a synchronous HTTP.call-request.
