How to use the imagecreatefromstring () function solution

The use of the imagecreatefromstring () function
Description on the manual: Imagecreatefromstring― Create a new image from the image stream in the string

I wrote this:

PHP Code

  
      Imagecreatefromstring ("Http://i3.sinaimg.cn/home/deco/2009/0330/logo_home.gif");

Error:
Imagecreatefromstring () [function.imagecreatefromstring]: Data is not in a recognized format

How should the parameters of this function be written?

Thank you!
