rendered OK. I'm not sure how to get them uploaded though. I dumped
them in the temp dir and tried using tilesGen.pl to upload them, but it only
grabbed the caption tiles and left the captionless behind. Is there a
different method for uploading these?</FONT></DIV>

<DIV><BR></DIV>The new lowzoom method uses a different process.
<BR><BR>The first step is to generate a lowzoom caption-only layer for
z8-z11. There's no layers.conf in svn that will do this at the moment,
but the one I use is included below.<BR><BR>You then have to upload this layer
and wait until it has be processed by the <A href="mailto:t@h">t@h</A>
server. Currently the next step expects to be able to download the
caption layer, and you don't get up-to-date results unless its
there.<BR><BR>The second step is to run the tools/lowzoom/lowzoom_composite.pl
script using the following arguments:<BR><BR>lowzoom_composite.pl x y 8 12
tile captionless caption<BR><BR>This will read the z12 captionless base layer
and the caption layer from z8 to z11 and composite these together to create
the tile layer which is what ultimately gets uploaded.<BR><BR>This approach
currently works best for z8 - z11, there is a projection bug which causes
captions to be misplaced at levels lower than z8, so usual tilestitching
method is still the best approach for z0 - z7.<BR><BR>There's a summary of the
approach here: <A
