Icon as an Image?

[David Ross]

Is it valid to have the SRC attribute of an IMG tag point to an
icon file (.ICO)?

I have a few pages that do this. See my
<URL:http://www.rossde.com/sitemap.html>.

This works okay with Mozilla. However, at my local public library
(which uses a clone of IE), all I see is the ALT text.

I use Mozilla as my Web browser because I want a browser that
complies with Web standards. See <URL:http://www.mozilla.org/>.

HTML validity cares nothing about the details of URL attributes, as
long as the appropriate characters are properly encoded.

Back around 10 years or so back, it was quite usual to specify
postscript files in <img src=...> attributes. I don't know any reason
in theory why one couldn't specify other kinds of resource: any client
agent which hasn't implemented your content-type is *supposed* to
display the alternative text, and offer access to your longdesc URL,
after all.
This works okay with Mozilla. However, at my local public library
(which uses a clone of IE), all I see is the ALT text.

So it's working as designed (as far as the alt text is concerned,
anyway - what about the longdesc?). And this is *despite* the fact
that IE brazenly lies about its Accept: abilities when retrieving
<img...> URLs, and therefore doesn't really deserve to play in this
particular game.

IIRC not really.

I use IE6 and the .ico file failed to load the first time I visited. Then I
entered http://www.rossde.com/editorials/safespace.ICO and the .ico file
appeared in the browser by it's self as I expected it would. Then I reloaded
the page and the .ico file appeared. I can only guess that downloading the
..ico file by it's self had some how trained IE to accept the file as a
legitimate web graphic even though IIRC it's not. I hope this helps.

So change it to a gif. It will look just the same.

Sorry to drag up an old thread, but it poped up on a google search for me and I've got an answer other people may find useful:

<!--[if IE]><iframe src="{STYLE_FAVICON_URL}" width="17" height="17" style="overflow: hidden;" frameborder="0" marginheight="0" marginwidth="0"></iframe><![endif]-->
<!-- If not IE --><comment><img src="{STYLE_FAVICON_URL}" width="16" height="16" border="0"></comment>

IE will display the favicon using the IFRAME (which unfortunatly needs to be 1px too big in both dimensions), and everything else will use the IMG tag (since only IE supports the comment tag)
