[OpenLayers-Users] Pink broken images

[Smaran Harihar]

Hi Gery,

Thanks for the reply, I was able to resolve some of the errors. Ok the
openlayer docs said that Geoserver is compatible with EPSG:900913 so I
removed any projections and it now overlays fine. But there is some shift
between my WMS base layer and OSM and GMap.

Also the new problem that I am facing is that  the lat and long that is
displayed in the control is fine if I display my WMS, but if I change the
basemap to OSM or GMap again the lat long goes haywire. Also the other WMS
with property 'isBaseLayer': false is overlaid on my WMS basemap but not on
OSM and GMaps. (Which was happening earlier).

Any suggesstions?

Thanks & Regards,
Smaran Harihar
