Sorry, I know this is for the wrong group - I just started here as the major
part of this app is related to a data base - this is just the fancy stuff at
the front. I have been able to get the screen to redraw by putting a
variable in the url that when set causes a meta tag to be sent with a
refresh option - it is ugly as it causes the screen to draw then immediatly
redraw. I have tried all combinations of header()'s but I am missing something.
Thanks,
Malcolm

I slved it with a javascript function - now I can't get the page refresh
to
work properly - I have implimented the ability to rotate the images but
although the image i rotated it's contents aren't. I have used all maner
of
header()'s to try and solve it but it only works when I physically hit the
refresh button on the browser.
OK well can you show us the code? As you dont give much to go on. BTW you
are posting to the wrong list you should use the PHP-General list as this
list is for database issues.
