in thread 404 image errors

If you made that an internal redirect rather than an external redirect, the browser wouldn't have to pull a second hit from the server... the server would merely substitute the image data.
... for (@image_extensions) { if ($url =~ /\.$_\z/) { print $q->redirect("/image/url/here.gif"); exit 0; } } ...
Now, about them babies... {grin}

    But would that still work if people are linking to my pictures from other sites?
    The load on the server doesn't matter, but as I log all the hits to the 404 page, the log file was growing enormous in a short space of time and I had to keep cleaning it out. When I told off the person who was generating the most hits, he got really annoyed at me, like it was MY fault that he was doing it wrong. But now every time he links to the wrong url, he'll have a picture there to tell him how stupid he is :)

      Of course. The only difference between an internal redirect, and an external redirect to the same server, is that the former is a lot easier load on your system. An external redirect will change the visible URL in the browser as well, but on an image, that's much harder to see. The net effect is that all "missing images" on your site will deliver the ugly picture as content, as controlled by the rest of the logic. (I did the same thing myself once... putting up a COWBOYS SUCK graphic to replace someone's deep-linked image from a Dallas Cowboy's fan-site.... they changed it pretty quick.)

      The rest of the code should be left the same (although only because I'm resisting the temptation to rewrite it).

      Eh, if you're logging actions, but the size of the generated logs is a problem, wouldn't the simplest solution not be to not generate those logs?

        I'm not logging actions, I'm just logging 404 errors - so that I can find out if there's anything going wrong.
