Thanks for any help. I've tried to post the minimum that demonstrates
the problem. (I use php to generate other pages, including some that
query mysql.)
When I access the html I get the actual jpg and two 'broken' images.
When I access the img1.php script directly the browser shows:
The image 'http://niof.net/tmx/img1.php' cannot be displayed, because it
contains errors.

</td></tr>
<tr><td>
<img src='img2.php' width=256 height=128>

Imagefill ($im, 0, 0, $clr1);
imagerectangle ($im, 10, 10, 190, 190, $clr2);
ImageJpeg($im,"newimg.jpg");
ImageJpeg($im);
ImageDestroy($im);
