That should be easy now that we have images.inc. That's where the
functions that deal with images are defined. The following code works:

<?php
include('./locale_en.inc');
include('./images.inc');
include('./phpweather.inc');

$metar =3D get_metar('EHEH');
$decoded_metar=3Dprocess_metar($metar);
?>

<img src=3D"<? get_temp_image($decoded_metar) ?>" height=3D"50" width=3D"20=
" border=3D"1">&nbsp;
<img src=3D"<? get_winddir_image($decoded_metar) ?>" height=3D"40" width=3D=
"40" border=3D"1">
<img src=3D"<? get_sky_image($decoded_metar) ?>" height=3D"50" width=3D"80"=
 border=3D"1">&nbsp;

The code is taken from the file tables.php which is also in CVS in the
phpweather-1.x directory. There you'll find a comprehensive test of
the functions that deal with images.

The problem is, that the precip_6h_in entry isn't a standard field in
the METARs. So you cannot rely on it being available at all times, if
at all.

Something like this would probably be better:

if (empty($data['precip_6h_in'])) {
  $precipin =3D 'None';
} else {
  $precipin =3D $data['precip_6h_in'];
}
