234656 - Initialize image tag with alt="" when Image not found or On error at Image Load

Status: RESOLVED DUPLICATE of bug 41924

(Firefox :: General, defect)

Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7a) Gecko/20040131 Firebird/0.8.0+

to suppress Ads I use a dummy ip address in host file for ad servers. If no alt
attribute is specified firefox  give a broken image  at place where there should
be an image. This is also annoying as a ad image, why not firefox automatically
initialize any image tag with alt="" if no alt is specified.

or alt=" " to take care off image as a links

If I understand correctly, you filed this bug because you don't like the
placeholder for broken ad images, and would prefer if the image disappeared
without a trace.  Should I change the summary to "Don't show placeholder for
images without alt text"?

If you used the "block images from server" option this would work so much 
better, since the browser knows the difference between a blocked image and a 
failed image load.  I don't like the idea of not having placeholders for busted 
images, because that might leave users with the impression that the browser is 
failing, instead of the server.  (We get enough bugs from people using 
the "from the originating site only" pref)

It can be an optional iten in preferences, but the browser should not modify the
sourcecode of a page. And the w3c says that user agents must show placeholders
of images...

Thanks, that is an option.

Still I like to see 
* a place holder when the image is about to load/loading.
* blank when image is broken

I just dont want to see page ugly, even when sever failed.
image broken indicator can be at status bar,
along with other things plugins needed, popup-blocked etc.

(Sorry for delay in reply)

i can confirm that broken images with no alt tag shows no sign of a broken image.
this is a duplicate of bug#41924 ?
