This is how you can compress the images while saving:
```python
import urllib2
import cStringIO
from boto3.session import Session
from PIL import Image
aws_session = Session(
aws_access_key_id=settings.AWS_ACCESS_KEY_ID,
aws_secret_access_key=settings.AWS_SECRET_ACCESS_KEY,
region_name=settings.AWS_DEFAULT_LAMBDA_REGION
)
s3_resource = aws_session.resource('s3')
im = Image.open(cStringIO.StringIO(urllib2.urlopen(image_url).read()))
w, h = im.size
w *= 0.5
h *= 0.5
im.thumbnail((w, h))
buf = cStringIO.StringIO()
im.save(buf, format="JPEG")
s3_resource.Object(bucket, filename).put(Body=buf.getvalue(), ACL='public-read')
```
I am reading images from a URL and compressing them and then saving to
S3 using boto.
See how and where you want to store your images and just change the
required line.
