[OpenLayers-Users] Pink broken images

[Phil Scadden]

As I understand it, geoserver reprojects vector layers on the fly, to 
the requested projection. OpenLayers sets that projection to be the 
projection of the designated base layer. However, I do not think that 
geoserver can reproject raster data on the fly and I would question the 
wisdom of doing so even if it could.
Reprojecting raster data is an operation fraught with difficulties and 
it is almost always better to return to base data from which the raster 
was based and create a new raster. This does of course create issues for 
creating transparent overlays on google maps. I do this by creating 
900913 versions of the raster data and putting those on geoserver 
instead. If you change baselayer from say google to a different one with 
a different projection, (as opposed to trying to display two at the same 
time), then projection of the OL map should change to the new baselayer 
projection.
