I noticed that form_for_* in newforms now carry deprecation warnings. This code is a minimal demonstration of how to use ModelForm as a replacement. Full information can be found on [Stereoplex](http://www.stereoplex.com/two-voices/django-modelform-and-newforms). Hope this helps you.
[The Session documentation](http://www.djangoproject.com/documentation/sessions/) rightly warns of the dangers of putting a session ID into a query string. Sometimes, however, you have to do it - perhaps your client has mandated support for browsers with cookies disabled, or perhaps (as in my case) you're just dealing with a slightly broken client browser. This middleware pulls a session ID out of the query string an inserts it into the cookies collection. You'll need to include it in your MIDDLEWARE_CLASSES tuple in settings.py, *before* the SessionMiddleware. *Please* read my [full blog post](http://www.stereoplex.com/two-voices/cookieless-django-sessions-and-authentication-without-cookies) about for the dangers of doing this, and for full instructions and examples.
A Django image thumbnail filter, adapted from code by [Batiste Bieler](http://batiste.dosimple.ch/blog/2007-05-13-1/). This updated version drops support for cropping and just rescales. You should use it in your templates like this: `<img src='{{ MEDIA_URL }}{{ image.get_image_filename|thumbnail:"300w,listingimages" }}' alt="{{ image.title }}" title="{{ image.title }}" />` This will produce a 300-pixel wide thumbnail of image, with the height scaled appropriately to keep the same image aspect ratio. 'listingimages' is the path under your MEDIA_ROOT that the image lives in - it'll be whatever upload_to is set to in your ImageField. If instead you wanted an image scaled to a maximum height of 140px, you'd use something like this: `<img src='{{ MEDIA_URL }}{{ image.get_image_filename|thumbnail:"140h,listingimages" }}' alt="{{ image.title }}" title="{{ image.title }}" />` Note the number has changed from 300 to 140, and the trailing letter from 'w' to 'h'. Please leave feedback and bug reports on [my blog, Stereoplex](http://www.stereoplex.com/two-voices/a-django-image-thumbnail-filter). I've only lightly tested this so you'll probably find something!
