Using PIL(/other?) to display resized images over the web?

[Steve Castellotti]

Hey all-

	Someone on the PIL mailing list suggested that I look into using StringIO
	when writing to the file. I had never used StringIO before, but after a
	little research I was able to figure out what I needed to know. For the
	sake of the newsgroup archive, here's sample code for the answer to my
	question:

#!/usr/bin/env python

import Image, cStringIO

sample_image = '/archive/sample.jpg' # The physical image path

file = open(sample_image, 'r')

im = Image.open(file)

format = im.format # remember to maintain image format when saving

im = im.resize((640, 480))

file_out = cStringIO.StringIO()

im.save(file_out, format)

file_out.reset()

print "Content-Type: image/jpeg\n"
print file_out.read()

file_out.close()
file.close()

Cheers
