[OpenLayers-Users] Using an SLD from Geoserver in my WMS request and the opacity isn't working for the fill

[Pere Roca Ristol]

  have you tested with "normal" PNG? 
  I have seen in
http://www.sitepoint.com/blogs/2007/09/18/png8-the-clear-winner/ that with
png8 pixels are either solid or completely transparent, but never partially
see-through.

  Geoserver 1.6.2 had a bug with png8 and empty images (not your case)
transparency.
