getimagesize very slow on remote image
<p>Good day,</p>

<p>I have a question here. I am trying to fetch image from few external sites as i'm trying to develop link sharing website for my project.</p>

<p>Right now i'm stuck at this part, </p>

<pre><code>getimagesize
</code></pre>

<p>It took basically > 100 seconds to get width and height of remote images. Is there any alternative method to reduce the time?</p>

<p>I tried sites like digg, facebook, image from external site appear very fast. How do they achieve it with any examples?</p>

<p>Thank you for your help.</p>
