upload external image and save it on my server
<p>I want be able to upload an image or just paste the URL of an image in order to upload it a sa profile picture for my website users. </p>

<p>the point is i dont wanna store the url but i want to have a copy of that image on my server because if that external image will be lost i dont want to lose it either...</p>

<p>i believe facebook and tumblr etc do so... what the php script or best practice to do that?</p>

<p>thanks!</p>
