Well, I latched onto the size value of the upload and figured okay, if
the value is greater than 0, then process the file
if ($_FILE['pageimage']['size']==0)
{
$processimage="no";
$imageinsert="$oldimage";
}
else
{
$processimage="yes";
}
But guess what?
IT STILL DOESN'T WORK! It won't even process the image now even
though the size is greater than 0!
I am stumped
PS James, thank you for your great info here. This particular area
