Why can netscape view animated gif when IE can't

[philosopherPlus]

I can see the following animated gif in netscape

http://www.mypracticalphilosophy.com/shelp/images/flydove.gif

but I can't see it in IE 6.0.2900.2180.xpsp_sp2_gdr.050301-1519

The IE tools option advanced tab is set to show animations.

Works fine on my IE 6.

Interesting -- I can't see it either --just a placeholder for the
picture.

Added the site to trusted sites, still doesn't work.

Downloaded the .gif, diplays and animates fine locally.

Googled google images for the flydove.gif image, lots of hits, all
displayed animation fine with no changes to my browser.

Attempted access to http://www.mypracticalphilosophy.com/shelp/images/
the directory of the images, got this server error message:

Attempted to "View | Source" for this page and the Source item is
grayed out -- so can't view the web page source code.

Somebody might want to invoke an HTTP sniffer here to see if there's
something in the HTTP header that would cause this problem.

If I connecting using a telnet app grab that URL I get an 85kb response that
includes a Content-Length header showing 104184. If I view it in Firefox
and save it it's the expected file size. Comparing the actual binary content
of the file and the raw HTTP data they are different. It's almost as if
there's maybe some compression going on, and when Firefox saves the file
it's decompressed, but IE is unable to deal with the "compressed" version
properly because the header indicates it's just a raw GIF file.

Dan:

It may not be HTTP-related after all. Note that the gif runs OK when
saved locally to your HDD, and is 104KB (as I recall).

I examined the IE cache file of the .gif (in IE5.Content) with a hex
viewer, and see it's prepared by "File assembled with the GIF
Construction Set from Alchemy Mindworks, Beeton, Ontario, Canada."

So perhaps there's some code embedded in the .gif which is preventing
its operation under IE6, or that IE6 is blocking some aspect of the
animation due to SP2's tighter default security settings. I didn't
explore all the settings, so I don't know.

It would be nice to know how to debug this nuisance. But for use of
the flydove.gif, just save it to disk and use it/forward it from there.

This comment block will not appear in files created with a registered version

So perhaps if the registered their shareware you wouldn't see this symptom
either. <eg>
