I don't know if it can be done but basically:

On page A there is a selection menu and the administrators can select an image they want. When selected the image would appear on page B to all visitors until it is changed again on page A.

Possible?
Thanks.

Totaly.

1. When Admin changes the "image" it is saved to a database.
2. Page "B" calls this database and displays the image.

If it is only one image, then I'd consider simply using a flat file.

PHP Code:

$image = $_POST['img']; // say there is a select box named 'img' that holds image SRC's
$fh = fopen('imgsrc.txt', 'w') or die('Could not open file for writing.');

fwrite($fh, $image) or die('Could not write to file.'); // Write the image src to the file

fclose($fh);

echo "Thanks, done."; 


PHP Code:

$imgsrc = file_get_contents('imgsrc.txt');
echo '<img src="' . $imgsrc . '" alt="" />'; 


Na, it's more likely going to be 4 or 5 images for the Administrator to choose from
