[OpenLayers-Users] question about example files

Mon Apr 28 22:46:09 EDT 2008

Thanks Chris,
That worked but now I have a single image that is being repeated over and over again.  What do I need to do to have the image tiled rather than repeated in each tile that appears in openlayers.
Thanks again for the help.
Todd

This might be because you haven't set the CGI variable "Map".
Specifically, you need to add a 'map' key/value pair to the params hash
(third arg to layer.mapserver).
