Hey all--
I have a simple photo website written in python. I would
like to be able to use Python Imaging Library (or similar) to read an
image file from the disk, resize/thumbnail it in memory, and then print
the modified image to stdout (sending it to the client web browser after
the proper MIME headings).
Currently, I have only managed to do this via
Image.save() to a temporary file and then sending that, but of course that
is somewhat inefficient. Surely there's an easier way to do this, perhaps
via file descriptors?
Cheers

The outfile argument to Image.save() can be a string (filename) or a
file object. You can send the image to the browser by saving the
thumbnail to sys.stdout instead of the temporary file name, i.e.
print 'Content-Type: image/gif'
print
im.save(sys.std out, 'GIF')
Cheers, Matt

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_ima ge, 'r')
im = Image.open(file )
format = im.format # remember to maintain image format when saving
im = im.resize((640, 480))
file_out = cStringIO.Strin gIO()
im.save(file_ou t, format)
file_out.reset( )
print "Content-Type: image/jpeg\n"
print file_out.read()
file_out.close( )
file.close()
Cheers

Hi.
I'm trying to create a stylesheet for a page that shows images instead of
text links. I tried to apply the FIR method but apparently that only works
for block-level elements.
Used HTML:

Does anyone know how to bind the image property of a picture control to an

My ASP:MENU uses images to create the buttons. Unfortunately, I can't

Hello,
I have a very big dilemma here, for me that is. I am using three images as BG's within a wrapper. See link. The top image is fine. But the center shows okay in design view. However, when I test, the content moves behind the center image. Also, my text is blacked out. This started happening recently.
Here it is in a nut shell. Box-1 contains images, text and box-2. This is repeated three levels vertically, with different images of...
