I did a little investigation of apache config solutions... The disadvantage to
the above system, as far as I can tell, is that it depends on having the image
load directly in the browser, while what we want is the image to load inline
with a page like opac-detail.pl.
A PHP solution was suggested to me in which the image tag point to a php file,
passing the ISBN as a parameter. The PHP file then checks for the existence
of the image, and if delivers it if found. If not it delivers an alternate.
Here's a snippet, with $img_location being the full path to the image file:
$buffer = @file_get_contents($img_location);
Here's the documentation for the file_get_contents if that helps explain:
I'm sure there's an easy Perl solution to match, but it's beyond my skills. If
anyone wants to step up I'd certainly be grateful.
