I have NO idea why some people were seeing that image.
I had a few emails about it but no one said anything about maggots.
The image that was supposed to be shown is just a flashing box with a notice that the link was expired.
I thought the flashing was what people were making a big fuss over
We're getting over 6 million image hits a month and almost a 3rd of that is for images that no longer exist or never existed.
So the error404 image was supposed to annoy the offending posters enough to remove or update the bad links.
But I think some previous bannage of greedy users was tripping other defenses and htaccess got a little confused

No wonder it's been a rough day
FYI., Dynamic Countdown sigs are limited to one per client. Some were posting 3 and more per post and that's really impossible for any server to keep up with for long
The image you should have seen is attached (I think)
