[imp] GD picture in IMP (quotabar)

[Krystian Filiks]

Hello,

I'm trying to generate a quotabar using PHP+GD but fail upon putting the
"header(Content-Type: image/png)" in to the header.inc file.

Below find the relevant part of the header.inc template, as soon as I
uncoment the // header("Content-type: image/png"); ?>
I get an error that the page could not be loaded as it contains errors.

If I keep the header("Content-type: image/png"); ?> commented then it works
fine just that the picture is displayed as text and not picture.

I know that the header("Content-type: image/png"); directive must be present
if I want to display the generateg PNG picture.

 Any ideas ho to make this work??

Filters on"), $imp['label']), 'menuitem') . Horde::img('filters.gif',
'alt="' . sprintf("%s %s", _("Apply Filters on"),
htmlspecialchars($imp['label'])) . '"') ?></a>&nbsp;
