Swapping text and pictures in Labels

merrymonk has asked for the wisdom of the Perl Monks concerning the following question:

Using Perl/Tk, I have a label that I want to use with both text and a picture.
To set the text I use

$text_replacement_res = $wg_name->configure(-text => $new_text);
[download]

To set the picture I use

$image_name_full = $image_loc . $new_image;
$image_use = $mw_Main->Photo(-file => $image_name_full);
$wg_name->configure(-image => $image_use);
[download]

where
$wg_name is the name of label widget
$new_text is the new text for the label
$mw_Main is the top level widget
$image_loc is the directory in which the image is stored
$new_image is the file name of the image

This allows me to:
Swap text for text
Image for image
Text for image
However it fails when I try and swap an image for text. What do I have to do to achieve this?
