<p>Hello and Welcome to this Wallpaperama "Get User's Screen Resolution" Script.</p>
<p>As webmaster, we often need to get the user's screen resolution to make our visitor's expirience more enjoyable and fun.</p>
<p>One way wallpaperama has implemented this, is to customize specific webpages to our visitors depending on the computer screen resolution
setting or properties.</p>
<p>The PHP function to do this is: <span class="style1">isset</span>(<span class="style2">$HTTP_COOKIE_VARS</span>[<span
class="style3">"users_resolution"</span>])</p>
