[ka-Map-users] First ka-map attempt..

[Paul Spencer]

Jeff,

on linux, you probably have the gd module compiled into PHP (that's the 
default and there is no good reason to have changed it) so you should 
probably reverse that change.

The 'flashing' tiles happen because the URL for the tile is somehow 
causing an error to be triggered.  ka-Map tries to reload images that 
fail in the hopes that a subsequent attempt will get the right image.

Imgaes can fail to load for a couple of reasons, but it most likely to be:

* tile cache configuration. Check the directory that you configured in 
config.php to see if it is being created.  It could be a permissions problem

* tile creation errors.  Check to see if any tiles are being created 
inside your cache directory.  If not, then it is likely a mapscript 
problem ... try to get a URL to a tile (using firefox, you can use page 
info and click the media tab, then load tile.php using one of these URLs 
... you may get some debugging output?

* check your apache error log for php/mapscript errors

Cheers

Paul
