OK, an update.  The pictures are saveable as .jpg's in Opera, so it seems to
be localized to IE.  Is there maybe a different set of headers that should
be sent for Internet Explorer, or do I just have a bug in my browser to deal
with?

 Remove the line:

 print jpeg formatbr;

 The error is because you have sent output to the browser before you are
 trying to send a header.

 I want to generate an image using the following code, and think it should
 have worked.  Unfortunately I get an error message saying the header info
 has already been sent, and the browser (IE5) doesn't print a picture just
 the
 characterset representing the picture.  I think I've got it right, but
 obviously, I don't.  Any help will be greatly appreciated.



   1.
   2.
   3.?php
   4.print jpeg formatbr;
   5.header(content-type: image/jpeg,replace);
   6.$image=imagecreate(200,200);
   7.$red=imagecolorallocate($image,255,0,0);
   8.$blue=imagecolorallocate($image,0,0,255);
   9.imagearc($image,99,99,180,180,0,360,$blue);
 10.imagefill($image,99,99,$blue);
 11.imagejpeg($image);

 ?
 html
 body

 img src=test.php alt=a php generated image
 /body
 /html



 what I get is the following:

 Warning: Cannot add header information - headers already sent by (output
 started at /www/ironorchid/stocks/test.php:3) in
 /www/ironorchid/stocks/test.php on line 5
 ÿØÿàJFIFÿþCREATOR: gd-jpeg v1.0 (using IJG JPEG v62), ...

 A printout of the jpeg file (I think) and a broken link icon.
