or even an HTTP question ;-)

and in /pmwiki/pub/script.php you should then set the HTTP headers 
appropriately, e.g.:

<?php

header('Content-type: image/png');
header('Content-Disposition: inline; filename="<PseudoFileName>"');
header('Content-length: <ImageSize>');

... print ImageBytes ....
?>

Then, using

<img src="/pmwiki/pub/script.php?parameter=value" width=".." height=" ..">

should show the image inline in the web page.
