Before calling the actual save (super), the thumbnail fields is dynamically created (using PIL). I am sure you can add code that will do the same thing for your "large" photo field. regards, Blue C -- You received this message because you are subscribed to the Google Groups "Django users" group.

Your eyes are weary from staring at the CRT. You feel sleepy. Notice
how restful it is to watch the cursor blink. Close your eyes. The
opinions stated above are yours. You cannot imagine why you ever felt
otherwise.

Re: Help getting started.....I think it is installed correctly
/home/mycode or /home is a linux location. Apparently, you are using windows. I would suggest creating a folder for all your django projects, say C:\DjangoProjects\ , and run django-admin.py from there. You do not want to put your django project folder in your www folder, since that may allow access to the sources themselves, instead of running them to create the html.
