I've just done a "file" on the generated tiles. It reports 8 bit. Even 
though I created with ImageCreateTrueColor!!!! Must be some obscure 
problem. I'll try doing a google search and see if that throws up 
anything.

BTW just noticed a mistake in the source of osm.php - it has 
ImageCopyMergr, not ImageCopyMerge. But I tested srtm.php (which doesn't 
use this) as well and still get the same result.
