Page is invalid. ALT tag is required.  Correct result is to collapse to alt 
tag.

If you specify width and height, it should ALWAYS take up that much space in the 
layout.

This also ends up being a performance issue, because you get a second relayout 
when the images don't make it - use this HTML as an example:

<img src="notreallyanimage" width=50 height=50>Hello

The results you get with that HTML is not right.

And the assertion about alt text is not correct - even if the image has alt 
text, this doesn't work

<img src="notreallyanimage" alt="a" width=50 height=50>Hello

erm oops, yeah it would still have the same dimensions. however, the page is 
still not in conformance.  Changing url to a permanent testcase, and 
redirecting to layout.

If an image is not available or is disabled or is otherwise broken, then it 
should be replaced by its alternative text. In CSS terms, the replaced inline
element becomes a normal inline element. 

Since 'height' and 'width' do not apply to normal inline elements, the place-
holder disappears.

INVALID.

See bug 1994.

verified invalid. exactly how it worked.

This really needs to be added to quirks mode.

This causes incredible layout problems.

Comment 14

[Marc Attinasi]

Reopened. For Quirks mode only. Nav 4.x and IE5/Win have the missing image
taking up the space...

Can we have a URI to a page that shows why this is such a major issue?

Please do read the arguments on bug 1994, bug 41924, and bug 23691.

i don't have a specific testcase, but some pages have broken images or
unreliable servers. and it does look a little more like it does in other
browsers, almost any other browser i know will show the broken image box in the
defined width and height. the quirks mode emulates so many really annoying bugs
that this cosmetic fix would fit in real well.

Comment 17

[alex.dent]

and one more thing: see how often this is reported as a bug, people just expect
it to leave the blank box, standard or not.

And I think people are too spoiled by high bandwidth.

There are still many people and many parts of the world that have slow 
bandwidth.

It is common to cancel a page before the images have loaded to save time. 
Without this bug fixed, these pages would suddenly relayout into a mess.

The whole point of quirks mode is to make things work the way they did in 
Netscape 4.x.

I can't imagine any justification for NOT putting this in quirks mode.

It worked this way on 4.x, it should work that way in quirks mode. Oh and by the 
way it works that way in IE.

And as far as standards go, why don't we try to get this changed? Why is it that 
when images are broken, the alt text goes to regular text, but when I turn off 
images in prefs, I still get the empty boxes. There is an utter lack of 
consistency here.

When people specify the width in height in images, they are doing it because 
they depend on the layout. So we should layout the width and height with the 
Alt Text in it. If standards prevent you from doing the right thing, change the 
standard.

And again, this is only a minor issue for people that have high bandwidth.

Try connecting over a 14.4 modem sometime (yes people still do that)

Sorry for the spam, and I realize this may be a dumb question, but...  What is
Quirks mode?  And how does Mozilla decide whether to use Quirks mode or not?  I
(like many other people) use images specifically for layout on my pages, so I'd
like to know how I can make sure my layouts won't break.

This page has a good explanation of quirks mode:

Moving to mozilla 1.0 to make room for more pressing stability issues in 0.9.1
