Sets the resize method of choice

$method can be one of the following:<br>
<ul>
<li>'resize' -> supported by every version of GD (fast but ugly resize of image)</li>
<li>'resample' -> only supported by GD version >= 2.0 (slower but antialiased resize of image)</li>
<li>'workaround' -> supported by every version of GD (workaround function for bicubic resizing, downsizing, VERY slow!, taken from php.net comments)</li>
<li>'workaround2' -> supported by every version of GD (alternative workaround function for bicubic resizing, down- and upsizing, VERY VERY slow!, taken from php.net comments)</li>
</ul>
