I was trying to see the gif by adding a border.  No luck here even!

sendGIF sends a picture to the page and then is supposed to fool the
browser into thinking the process is done, so it can continue loading,
while the php script keeps running.

Ahhh, that does look bad!  Pardon my typo...  Even so the sleep
command executes regardless.  So this shouldn't be the explanation for
why the script is not running separately.

This is the path from where?  From my root web directory?  On apache,
would it be from htdocs for example?  That is if zap is a top level
directory in htdocs it would just be "/zap/news...".

Thanks for trying.  I'm probably going to have to go with cron if I
can't get this to work but I tried.  : )

Do you think it would work to put a simple call to send news in a hidden frame?
