Using PIL with CGI scripts

Mark:

Sorry for bothering you again, but I can't figure out how can I do this 
work.

I can`t write the image to the disk because all of the images are inside a 
single file where they are compressed using pickle. What I'm trying to do is 
to get some images from this file according to a word search perform by the 
user of the web site. This part is already done, so the images are extracted 
from the file but they are in a PIL format, ie they are an Image type, and 
for that i cannot display them in a web page using the HTML tag <IMG SRC = > 
because this tag only accepts a file name as input.

I try to use cStringIO to emulate a file, but I don't know how I must use 
this variable with the HTML tag.

This part of the code is something like this:
from cStringIO import StringIO

print "Content-type: text/html"
print
print "<HEAD><TITLE>WEBIMAGE</TITLE></HEAD>"
print "<BODY BGCOLOR=\"#FFFFFF\" TEXT=\"#000000\" LINK=\"#0000FF\" 
VLINK=\"#000080\" ALINK=\"#FF0000\">"
print "<center><H1>WEBIMAGE</h1>"
print "<p>Version 0.01</p>"
print "<hr>"
.
.
.
temp = StringIO()
im.save(temp,"JPEG") #im is an Image variable
temp.seek(0)
print "<p><IMG SRC='%s'>"%temp

print "</center>"
print "</body>"

Hope you can help me and thanks in advance
