106719 - image onError handler - not loading alternative picture

Status: VERIFIED DUPLICATE of bug 22820

(Core :: DOM: Core & HTML, defect)

Description

[Hungerburg]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5+) Gecko/20011025
BuildID:    2001102508

the page http://www.tiroler-landesmuseum.at/webcam/weboverview.html displays
images taken with a webcam. a javascript computes the image names. sometimes
pictures are not captured. the image cannot be found and the onError handler is
used to load another picture instead.

mozilla does not display this alternative picture, though its name appears in
the "page info" dialogue.

when mozilla once decided to show the alt text instead of a picture, it will
never display another picture put into its place by javascript.

there has been a change in behaviour since 0.94, so that when the page loads
with an image in place, mozilla now does not display the alt text, if a missing
one is put in there, but keeps the one already there.

Reproducible: Always
Steps to Reproduce:
1.go to http://www.tiroler-landesmuseum.at/webcam/weboverview.html
2.click on "voriger Tag" (previous day)
3.watch the images change, or not ;)

Fabian Guisset, its not a duplicate of your bug, but its a duplicate of #22820.
practically, its about part of the usefulness for the onError handler.

changed bug status (if I may.) put up a simpler test case
