opening remote image and saving it

[dalar]

hi there,

I would like to write a script that does the following:

1. opens an image from a remote location
2. saves the image from the remote location to my local machine (where the php script is).

As an example, can you give me some hints on how to write a script that opens up the google image url which i think is http://www.google.co.uk/intl/en_uk/images/logo.gif and will save it to where ever I want to (eg. same directory).

Thanks
