Update ...With a Question ... I changed this:
while($row = mysql_fetch_array($result))
{
printf ($row["photo_name"]);
foreach($row as $key => $value)
{
$my_array[$key] = $value;
}
} //array now full of results from previous query
to this ....
while($row = mysql_fetch_array($result))
{
$my_array[] = $row["photo_name"];
}
and $my_array[] now stores the corrent number of image names!! Why does the
foreach(....) duplicate the entries?
