A Django form field that accepts an uploaded image and creates a resized image attached with a push-pin

PushPinImageField is a Django form field that is a sub-class of an ImageField. The field accepts an image to upload and based on certain settings, notably the size of the resulting image, the sizes and colors of 3 different borders, as well as the color of the push pin, a re-sized image is created with a colorized push pin in the top-center. A live demo of the field as well as more detailed usage instructions are available as a [blog entry](http://www.robmisio.com/blog/2/).

EncryptField

I was trying to create a custom field to use the mysql encrypt() function on some data I wanted to store in the DB. initcrash on IRC pointed me to [this code](https://tracpub.yaco.es/cmsutils/browser/trunk/db/fields.py?rev=66) which I butchered as best as my little brain could. Amazingly enough I got it working (thanks to a couple answers from initcrash). If anyone can clean this up that would be great. I'm also trying to figure out how I can a) create password reset link in the admin interface for this field without displaying the field or b) decrypt it so that the password field is pre-populated with the decrypted password. Otherwise it is submitting the encrypted string as a new password. Anyways, I'm only a week or two into Django with no python experience so any suggestions are very welcome. Hope this helps someone!
