I'm using a Tk::Text widget to hold and flip through images. If the image is too big to fit on the screen I do a quick resize (hence the two Photo objects).

The program works fine, except that it eventually crashes with "out of memory" issues.

I've looked for similar questions and documentation on this where I can, but don't see how, after I've destroyed the Photo widgets and deleted the image from the Text widget these are still building up in memory.

I used to display the images on a button and had no issues with destroy and memory leaks there, so I suspect imageCreate() is at issue. So what do I do to fix this? Change my approach, or some other trick to free that memory up? Thanks. 
sub show_next_image {
    my( $id, $filename ) = get_next_pic();
    my $raw_image = $Image_Window->Photo( '-format' => 'jpeg',
                                          -file => $filename );

    my ($img_w, $img_h) = ($raw_image->width, $raw_image->height);  
    my $max_width = $Main->screenwidth()-20;
    my $max_height = $Main->screenheight()-75;
    my $xfactor = $img_w / $max_width;
    my $yfactor = $img_h / $max_height;

    my $intfactor = $xfactor > $yfactor ? int($xfactor) : int($yfactor
+);
    $intfactor += 1;

    my $image = $Image_Window->Photo();
    $image->copy( $raw_image,
                  -subsample => $intfactor);

    my $reduced_flag = ( $raw_image->width == $image->width ) ? 
        'full-size' : "reduced by $intfactor";

    $Image_Window->delete( '0.1', 'end' );
    $Image_Window->insert( '0.1', "$reduced_flag\n" );
    my $image_widget = $Image_Window->imageCreate( 'end', -image => $i
+mage );

    $raw_image->destroy();
    $image->destroy();
}
