There are several ways of serving static files from Zope. The simplest way is to just do something like this:
size = os.stat(file_path)[stat.ST_SIZE]
REQUEST.RESPONSE.setHeader('Content-Type','image/jpeg')
REQUEST.RESPONSE.setHeader('Content-length',int(size))
return open(file_path, 'rb').read()
The disadvantage with this is if the file is say >1Mb, the whole 1Mb needs to be loaded into RAM before it can be sent. This is surely garbage collected afterwards but if you serve many of these at the same time, there's obviously the risk that the RAM gets too full.
The alternative is to use filestream_iterator from the ZPublisher which is an iterator that sends out chunks of the file at a time. Note that to use the filestream_iterator you must set the Content-Length header first. Here's how to use it:
from ZPublisher.Iterators import filestream_iterator
...
size = os.stat(file_path)[stat.ST_SIZE]
REQUEST.RESPONSE.setHeader('Content-Type','image/jpeg')
REQUEST.RESPONSE.setHeader('Content-length',int(size))
return filestream_iterator(file_path, 'rb')

This is silly but fun. I can with one command on the command line start updating my Facebook profile. It's not using the Facebook Developer API but a PHP script I copied from some other blog I can't find right now. Here's how I use it:
