Another way is to use BytesIO. BytesIO is like a buffer. So one can save the image (which is fast enough than writing to disk) in that buffer.

from PIL import Image, ImageDraw
import io

def chart(request):
    img = Image.new('RGB', (240, 240), color=(250,160,170))
    draw = ImageDraw.Draw(img)
    draw.text((20, 40), 'some_text')

    buff = io.BytesIO()
    img.save(buff, 'jpeg')
    return HttpResponse(buff.getvalue(), content_type='image/jpeg')
