Which is better for faster browsing speed? download different images from different site/one site for a webpage's images [HTML/PHP]
<p>[ I am not sure <strong>StackOverflow</strong> is the right place to ask the question because it is slightly related to programming ]</p>

<p>Suppose my web page needs 2 images to display . Now I have two options before displaying them into my <strong>HTML</strong>/<strong>PHP</strong>:</p>

<p>1) Upload all of them in one site 
( Is it faster ? because everything is in one place)</p>

<p>2) Upload them in different site
( Is there any pipeline effect ? ) </p>

<p>for example : I have two images : <strong>a.jpg</strong> and <strong>b.jpg</strong> to display . Now Which upload is better for browsing speed to my webpage?</p>

<p>Either :</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;head&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;img src=website1.com/a.jpg&gt;
&lt;img src=website2.com/b.jpg&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>Or :</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;head&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;img src=website1.com/a.jpg&gt;
&lt;img src=website1.com/b.jpg&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>Or there is no effect ?</p>
