18543	Non image file can be saved to ImageField	johnsmith		"https://docs.djangoproject.com/en/dev/ref/models/fields/#imagefield
    Inherits all attributes and methods from FileField, but also validates that the uploaded object is a valid image.


I was trying to find out the exact exception that would be raised if a file is not an image and it appears that no such image validation is done. So I did a test, with a model such as this
{{{
class Image(models.Model):
    caption = models.Charfield(max_length=60)
    image = models.ImageField(upload_to='somewhere')

}}}

I tried this
{{{
f = django.core.files.base.ContentFile('not an image')
i = myapp.models.Image()
i.caption(""This should throw an error but doesn't"")
i.image.save('bar.jpg', f)
i.save()
}}}

I don't get any errors and the file is saved. Maybe I'm doing something wrong but from what the docs say I'm expecting to be prevented from doing this.
