There seems to be original functionality in Netscape (3 and 4 at least) that
allows you to post images using script in some sort of stream.
This software:
is used here:
To "stream" "video" from a webcam

Reproducible: Always
Steps to Reproduce:
1. Go to
2. Using Mozilla and Internet Explorer you get nothing
3. Using Netscape Communicator 4 and Netscape Navigator 3 you see image changing.

Actual Results:  Don't see anything

Expected Results:  See the stream

WFM on WinNT 4 2001080203

You may have to wait a while for the streaming image to come up.
Please try a later build from

Using 2001080203
The original URL:
doesn't show image at all.
You should try Netscape 4 to see what I mean, because there is also a Java
scroll on the top - that's not what I meant.

I can see the same images in both NS 4.7 and Mozilla: 
two banners at the top, and below them a big webcam image that it is updated
once a minute.
The difference is that in NS the throbber and status bar keep on showing that
something is downloaded, but in mozilla they stop after the initial image is shown.

I really cant verify this bug. Nav4.x and Mozilla shows the same to me. But I
think  76776 is about a different problem. Bug 76776 is about "progressive JPEGs". 

(see )

This bug is about "Server PUSH". Server PUSH is about streaming multiple content
on a HTTP response

I can now confirm (after fixing my setup) that I do see the desired result (at 
least sometimes). Sorry about that.
Problem is that I can only do that once per stream. Second time I go to that 
page, or just try to reload it, nothing shows up. I can go to another stream and 
it will work, but again, only once.

Also, when I try to close Mozilla after that (to try again) it sometimes 
crashes. That only seems to be that case with Java enabled, so it is probably 
another bug (I use JRE 1.3.0_01)

Here are URLs that I used in last test
