Please extract file (adres is in URL forum) and open that page, then move mouse 
to the left on the pictures (they are links) and pictures disappear so you

disappear but the place where images would be appear as a free space and you 
can click on it.

Reproducible: Always

ok, this page is evangelism

on every mouseover of an image the js console gives an error: ReplaceMe is not
from source:

 <div class=opis id=ReplaceMe></div></td></tr>
<td vAlign=top><a onmouseover="img_on('Main'); window.status =
'G?ówna';&#13;&#10;&#9;&#9;&#9;ReplaceMe.innerHTML = 'Strona
G?ówna';&#13;&#10;&#9;&#9;&#9;return true" 

etc.there's no document.getElementById("ReplaceMe") anywhere.

if Marcin hasn't written this, we need to find contact data.

I can contact the author but I do not see what exactly he is supposed to change. 

JavaScript is not my virtue. It is clear that the code is IE4+ specific. It
would see to me that something like

<div class=opis id=ReplaceMe></div></td></tr>
<td vAlign=top><a if (document.getElementById){
onmouseover="img_on('Main'); window.status =
'G?ówna';&#13;&#10;&#9;&#9;&#9;dupa.innerHTML = 'Strona
G?ówna';&#13;&#10;&#9;&#9;&#9;return true"}

is standard compliant and should work with both IE and Mozilla but it still
gives "dupa not defined" error. Trying
document.getElementById("ReplaceME").innerHTML in place of ReplaceMe.innerHTML
results in a syntax error, too.

Is this because the code is embedded inside <a> </a> tags, instead of <script>

Ferdinand: Could you be more specific how to repair this? It would help a lot in
my communication with the page author.

OK. I got it. Forget what I wrote above. It should be:

everywhere where we have ReplaceMe.innerHTML

Take note of the single quotation marks as this happens inside the standard ("
") quotation.
It seems I learned a lot of JavaScript today :-(

BTW, the vanishing pictures are the result of not copying the *_on.gif files
which are used

The corrected complete of files can be found at
The only difference except copying all graphic files is the above mentioned
change in Menu.htm.

I changed the summary as the disappearing images were the result of missing
pictures used with onmouseover and onmouseout.
Summary: Links on images disappear when coursor is on it. → IE specific dynamic content method on

The author of the page was notified about the error and the proposed solution.

I know that when you add "missing pictures used with onmouseover" page will be 
displayed properly, but when you don't have "missing pictures" page in Mozilla 
is displayed as I wrote above "disappearing pictures" (that is the thing I want 
to report) in Opera pictures didn't disappear just are the same as before mouse 
move, in IE 5.5 SP1 it disappear but the place where images would be appear as 
a free space and you can click on it.
Please check the second page and you 
get the same effect.

I probably know why that is happen, when IE can't load some images the place 
where images should appear as a free space [] 
the same site in Mozilla [].
As you see in Mozilla you don't kown that 2 images wasn't loaded. So back to 
subject when you move mouse on javascript buttons (they aren't loaded) they 
just like above 2 pictures disappear/didn't displayed.

I believe you've hit the problem decribed in bug 92284. Read this comment by
Doron Rosenberg on 2001-08-31:

>what  the reporter means is, when you onmouseover over the images, the image is

> downloaded. Other browsers keep the old image shown until the new one has been
> fully fetched. 

The image disappears in absence of the new one that should replace it, exactly
because it is replaced by the black placeholder box. So this part of the bug is
a dup of bug 92284. I will mark the the remaining "Evangelic" part fixed when
the page is changed to use document.getElementById.
