Django Image Helper

Provides a model mixin that has 'image' and 'thumbnail' fields. The uploaded image will be scaled to the model's 'IMAGE_SIZE' and a thumbnail will be scaled and saved to the model's 'THUMBNAIL_SIZE'.

Additionally, there is an admin mixin to help you display an image's thumbnail when in the admin's listview.

RELEASE NOTES:

version 0.1.1 Added AdminImagePreviewWidget. This will show a preview of the image in the admin change_form view in addition to the link the admin already shows.

To enable, add the following to your ModelAdmin.

formfield_overrides = {
    SizedImageField: {'widget': AdminImagePreviewWidget},
}

version 0.1.0 Added SizedImageField. This lets you do the same thing the ImageMixin was used for, but isolates all the work to the model's field. It should work with any storage backend.

See the example project for a working sample. The basics:

class MyModel(models.Model):

image = fields.SizedImageField(upload_to="the_directory", size=(500, 500), thumbnail_size=(200, 200))

Then you can access both the image and thumbnail in code or templates by:

model.image.url model.image.thumbnail.url
