[ZendTo] statistics image errors

[bbrendon at gmail.com]

The only obvious thing is that notfound.png is actually in
zendto/www/images/notfound.png. I'm not sure why its looking
under NSSDROPBOX_DATA_DIR. Also, the apache error log is at the end. I
don't think this feature has ever worked. I just ignored it for the longest
time. I just updated to the latest version and thought I've try it again.

Any hints would be great!

My NSSDROPBOX_DATA_DIR :
define('NSSDROPBOX_DATA_DIR','/u0/zendto-storage/');

And inside that is...
$ find .
.
