copy() and ImageMagick
<p>I'm coping external file with <code>copy()</code> and then resize it with ImageMagick.
Will php wait until image been downloaded and only after that begin converting image ?</p>

<p>For example</p>

<pre><code>copy("http://sstatic.net/stackoverflow/img/sprites.png","newfile.png");
</code></pre>

<p>Here I convert downloaded image <code>exec("nice -n 19 convert -resize 500x500 ....</code></p>
