[Zope] Set MIME type using ZPT

[srikanth]

Hi,

  I am using an external method to load an Image from the harddrive. The
external method is as follows:

from email.MIMEImage import MIMEImage
##parameters=filename
def getDocument(filename):
      fname = '/mnt/'+filename;
	input = open(fname,'r')
	content = MIMEImage( input.read( ) )
	input.close( )
	return content


When I try to display the content in the webpage what I actually got is
all raw data of the file rather the image. 
So how can I convert the raw data to be dispalyed as image in the
webpage. I am using ZPT to display the web page (image). If its dtml I
could have used <dtml-mime> tag is there any equivalent to that in ZPT.

Any suggestion would be a gr8 help.

Ta.
