I am trying to upload an image through the Django Admin Panel. I am running on Google App Engine and using the filetransfers plugin (not sure if either is relevant to the problem I am having).

From my modelys.py:

```
from django.db import models

# Create your models here.
class CarouselItem (models.Model):
    caption = models.CharField(max_length=200,blank=True)
    order = models.IntegerField()
    carousel_image = models.ImageField(upload_to='uploads/carousel_image/%Y/%m/%d/')
    def __unicode__(self):
        return self.caption

```

From admin.py:

```
from carousel.models import CarouselItem
from django.contrib import admin
from imperavi.admin import ImperaviAdmin

class carouselAdmin(ImperaviAdmin):
    list_display = ('caption','order')

admin.site.register(CarouselItem, carouselAdmin)   

```

The error I am getting is "No module named Image". I don't have PIL installed. Do I need to install it to enable this functionality?

Update: here is traceback that caused error:
