    If it helps to narrow it down, I believe it the problem is specific to
    either 5.0 or 5.01 -- I ran 5.5 on Win98 SE, and now WinME, and have not
    had a problem with the images loading.

    Far be it from me to add fuel to the fire on this one, but is it 100%
    certain that the server is sending the correct MIME types?  The reason I
    say this is from the following scenario...
    
    1) Where possible on my personal site, I have attempted to use content
    negotiation just as the validator does; hence, if a page is valid, I will
    have a badge which points to
    "http://w3.one.net/~gilkison/img/valid-html401" (no .gif or .png
    extension, as my ISP supports content negotiation)
    
    2) If I validate my a page at my site
    (http://w3.one.net/~gilkison/genealogy/ for example) then the validation
    results page shows two different badge images.  If I right-click on the
    image in MSIE (the one before the "Congratulations" text), and select
    "Properties" from the popup menu, then I see an 'Address (URL)' of
    "http://www.w3.org/Icons/valid-html401" and a 'Type' of "File".
    
    3) If, from the results page, I go directly to the validated page, and
    right-click on the Valid HTML at the bottom of my page, then the exact
    same image displays an 'Address (URL)' of
    "http://w3.one.net/~gilkison/img/valid-html401" and a 'Type' of "GIF
    Image".
    
    Point #3 tells me that MSIE is seeing what it considers a valid content
    type from my ISP, but not from the Validator (#2); regardless of the site,
    MSIE 5.5 displays the correct image for me (and as I type this, I'm
    running MSIE on Win95 at my office, so I don't think it has anything to do
    with the OS version).
    
    From a diagnostic standpoint, my version of MSIE appears to present
    "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*" in the
    HTTP_ACCEPT header...
    
    Is there any chance the server compress the content in any way?  I found a
    reference in MS Knowledgebase to problems with compressed content --
    "Internet Explorer 5.5 Does Not Allow Compressed Content Over HTTP Version
    1.0" (http://support.microsoft.com/support/kb/articles/Q274/8/03.ASP)...
    
    Just throwing out my $.02 in hopes of solving this...
