Re: Problem updating data

[Blue]

My first thought is that you didn't call parent save method in you
custom save method

super(YourClass, self).save(*args, **kwargs)

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

[Blue Cuenca]

/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.

You may want to look at this:
http://snipt.net/danfreak/generate-thumbnails-in-django-with-pil/

The snippet above overrides the save method.  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.
