Python: Download image file from URL and retrieve common properties

With the following snippets, you can get yourself:

• Image width/height
• Image mime type
• File size

So, the code snippet!

view sourceprint?

01.from PIL import Image

02.import urllib2

03.import cStringIO

04.import os

05.from stat import ST_SIZE

06. 

07. 

08.file = cStringIO.StringIO(urllib2.urlopen(image_url).read())

09.filename = "/tmp/file_%s.jpg" % datetime.datetime.now().strftime("%s")

10. 

11.image_info = Image.open(file)

12.image_info.save(filename)

13.file.close()

14. 

15.file_info = os.stat(filename)

16. 

17.filemime = "image/%s" % image_info.format.lower() # JPEG, PNG, GIF

18.width, height = image_info.size

19.filesize = file_info[ST_SIZE]

From Doug Hellmann's blog:

The cStringIO version is written in C for speed, while StringIO is written in Python for portability.

Once you're done, remember to delete the temporary file.
