<DIV><FONT size=2><FONT size=3><SPAN>Hi all, </SPAN><BR><BR><SPAN>After having
successfully managed to get TileCache working with my WMS layers i am now trying
to include a layer which has labels. These labels aren't getting drawn when they
are near the edge of any tile, a problem i see a few users have come across.
</SPAN><BR><BR><SPAN>The solution has always been something like adding the
following to one's tilecache.cfg: </SPAN><BR><SPAN><B
class=highlight>metaTile</B>=<SPAN
class=723572905-28052008>true</SPAN></SPAN><BR><SPAN>metaBuffer=40
</SPAN><BR><BR><SPAN>I have now tried this, and I receive the following error
from any tile through Firebug. </SPAN><BR><BR><SPAN>An error occurred: No module
named Image </SPAN><BR><SPAN> File

practice?): </SPAN><BR><BR><SPAN>[free_elevation] </SPAN><BR><SPAN>type=WMS
