Eric,

I agree that 3000x3000 is quiet large :-) I did that cause i thought the 
labels were wrapping, i tryed 300x300 but still the same labels on the 
wrong spot. I tryed editing the label object associated with the legend object:

===============
$lg=$map->legend;
$lg->set("width", 100);
$lg->set("height", 100);

$my_lg_label = $lg->label;
$my_lg_label->set(wrap, 0);
$my_lg_label->set(partials, 0);
$my_lg_label->set(offsetx, 20);
$my_lg_label->set("color", $map->addColor(0,0,0));

$legend_img=$map->drawLegend();
$legend_url=$legend_img->saveWebImage(MS_PNG,1,1,0);
================

It looks a bit better (see attachment), but the legend labels are centered 
and cut off at the beginning. I'm now sure why the labels keep centering, 
cause i nowhere specified that they should center.
