Google Earth transparency

[Jørn Vegard Røsnes]

Thanks Wim,

this did the trick.
It works if I use gif and annotations/text in grey.
Unfortunately is the text rather unreadable, so I consider using WFS and XSL 
for KML translation.

If I use png I get an error message in Google Earth "Unsupported image 
format".
This could be related to the poor graphics card in my notebook, ref.

I'll try it out with better HW also.

I use Miller projection (epsg:54003) in my shapefiles.

cheers
Joern
