Lars, thank you for your effort and willingness to help. Unfortunately,
we have a way to go yet for success:
$uvquery = "SELECT `uv_filename` FROM 'uvphotos' WHERE `species_name`=
$speciesname";
That should probably be
... FROM `uvphotos` WHERE `species_name` = '$speciesname'";
When I substituted this suggestion I got the following error:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ''uvphotos' WHERE `species_name` = ''' at line 1
or better:
...WHERE `species_name` = '".mysql_real_escape($speciesname)."'";
When I tried this, I found more information on mysql_real_escape() at:
http://php.net/manual/en/function.mysql-real-escape-string.php
With this proof that it is a valid function, it is hard to understand the
error I got when I used your second suggestion. I was surprising:
Fatal error: Call to undefined function mysql_real_escape() in
/home/content/b/i/l/billmudry/html/taxa/show_uv_photos.php on line 69
Sooo ..... I will wish you and anyone else the best but we are not at
a working solution yet.
I was thinking of listing only the section of interest but just to be
on the safe
if not complete side, I will list below the full page code as it stands.

// Program: show_uv_photos.php
// Description: This program displays Uv fluorescence photos of wood
found to glow under an ultraviolet
// light. This is around 10% - 15% of all wood species.
//
// It runs as a pop-up window and is activated by a button titled
"U.V. Fluorescence" generated by
// displayspecies.php. Future code may be added later to display the
buttons only if the program can
// detect UV photos stored for each species.
// PARAMETERS:
// {$_SESSION["speciesname"]} - Looks back to find what the
current species picked is.
// speciesname - The session variable name for the
cuurent species.
// $speciesname - The standard variable name taken from
the session variable.
// species_name - the name of the column that stores up
to over 15,000 different botanical naes of wood.
// uvphotos - the name of the table in the TAXA database
that holds the partial path and photo file
