Max files in unix folder from PIL process

[David Pratt]

Hi.  I am creating a python application that uses PIL to generate 
thumbnails and sized images. It is beginning to look the volume of 
images will be large. This has got me to thinking.  Is there a number 
that Unix can handle in a single directory. I am using FreeBSD4.x at 
the moment. I am thinking the number could be as high 500,000 images in 
a single directory but more likely in the range of 6,000 to 30,000 for 
most. I did not want to store these in Postgres. Should this pose a 
problem on the filesystem?  I realize less a python issue really but I 
though some one might have an idea on the list.

Regards,
David.
