He dele454,
you cannot set HTTP-EQUIV meta-tags on an image... These are (X)HTML-tags to
be used in (X)HTML-pages - images on the other side are send as binary data
in the according format (JPEG, GIF, PNG for example), adding meta-tags to
these data-streams has no effect other then corrupting the image data.
You have to set the response headers in your action accordingly:
<?php
$this->getResponse()->setHeader('Content-Type', 'image/jpg');
$this->getResponse()->setHeader('Cache-Control', 'no-cache');
[...]
?>
Best regards
Stefan

->appendHttpEquiv('pragma', 'no-cache')
