If you fetch the url with mozilla, you'll notice that the images
looks like an animated one. This is wrong.
I generate a random image with this script, and fetching it once
seems to lead to downloading it twice, hence the feeling of animation.


Reproducible: Always
Steps to Reproduce:
1.fetch the url
2.look at the arrows, they move once


Actual Results:  you see 2 arrows, then they move to a different place.

Expected Results:  you see 2 arrows, still.

Sounds also a lot like Bug 121084 (The testcase URL there is a similar script)
Depends on: Heidi
Concerning the cache comments (of <a 
href="http://bugzilla.mozilla.org/show_bug.cgi?id=121084">Bug 121084</a>, I've 
done a few things to try to avoid the bug :
1- I Added "Cache-Control: no-cache" in the headers of my HTTP response;
2a- I cleaned both memory and disk caches, and restarted Mozilla
2b- I also tried without a restart of Mozilla

the image is still loaded twice.

bug still is present in build ID 2002072104

Bug still there with ID 2002091014.
My current configuration is windows XP :
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910

Hey this *looks* fixed !
Yeah, I can not seem to reproduce this anymore with BuildID 2002101719 on Red
Hat Linux 8.0
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021130

The image does not change except when you reload the page.
Bug seems to be fixed.
To me it seems to be WFM too.
