here is a function to read the contents of a directory that then pulls it
into a drop down select list. You may want to modify it for your needs but
this should work for you.
$dir_name = "/virtual/path/to/images/directory/";
$dir = opendir($dir_name);
$file_list .= "<p><FORM METHOD=\"post\" ACTION=\"images_done.php3\"
NAME=\"images\">
<SELECT NAME=\"images\">";
while ($file_name = readdir($dir)) {
if (($file_name != ".") && ($file_name !="..")) {
$file_list .= "<OPTION VALUE=\"$file_name\"
NAME=\"$file_name\">$file_name</OPTION>";
}
}
$file_list .= "</SELECT><br><br><INPUT TYPE=\"submit\" NAME=\"submit\"
VALUE=\"select\"></FORM></p>";
closedir($dir);
