PHP further process result of ImagePNG() without saving to disk?
<p>Is there a way to process created image (using <code>ImagePNG()</code> from GD library) in memory <em>so to speak</em> without need to save temporary file to disk? What I am trying to achieve is basically to POST created image and would like to avoid any need to create temporary files, if possible. PHP would just output response of that POST from server.</p>

<p>Thanks</p>
