Thank you very much for your answer Troy, but I have still problems with your fourth step (the img tag), because I'd like to display the image from a DTML document not from a page template. Obviously, something like: <dtml-var data_of_the_jpeg_file> doesn't dsiplay an image but the content of the jpeg file, so do you know how to fix this problem? --- Troy Farrell <troy@entheossoft.com> wrote:
This is an interesting request. Almost certainly, you do not want to do this, but if you do, you will want to
1) verify you have a session object (REQUEST['SESSION'] by default) 2) store your data there (REQUEST.SESSION.jpg_image = '^JPEGNONPRINTABLECHARSHEREk...' 3) create a python script that returns the image:
if REQUEST['SESSION'].has_key('jpg_image'): img = REQUEST.SESSION.jpg_image else: img = container.substitute_image.data
return img
4) call the method from an img tag: <img alt="my image stored in a session" src="python_script_name" /> Note that you'll have to calculate height and width on your own...
That's a rough guess. It won't work without some messing around, but that's how I would approach such a challenge. I hope your server has a decent amount of RAM :)

Please do not mail me personally, mail to the zope list instead (I have CC'd it), especially since I know nothing about sessions.

Hi Sir!
Do you know how to store the content of a jpeg file for instance within a session, then display this content of a jpeg file as an image?
Thank you very much for your help,
Tibo.
cheers, oliver
