Hi Denis,

Thanks a bunch for your help. I liked your solution a lot and tried
to implement it with only partial success. Below is the URL for a
test page of what I have implemented with your code. The page
appeared blank until I commented out the here document. I also
implemented var_dumps on the variables to be sure I was getting
accurate data.

http://www.geol.ucsb.edu/graduate/aa.php

I also corrected a couple of syntax errors but mostly the code is
exactly as in your code above.

This is what is commented out:

//echo <<<EOT
//
//<img src="http://www.geol.ucsb.edu{$imgfile}" alt="{$captiontext}" /
>
// 
//{$captiontext}
//EOT;

As you can see, it appears fine with the here doc commented. I just
can't see what is wrong with the here doc. Thanks for any further
help.
