Answer 1

A key question is: when should the thumbnail be generated?

1. Dynamically when the user requests a thumbnail image?
2. Or do you want to create a physical disk file whenever a country is INSERTed/UPDATEd in the database.

If (1) I suggest you create a view that maps to url /flagthumbnail/countryid. The view method would then have to:

1. Get the country instance from the database
2. Read the flag image into a PIL Image and resize that.
3. Create (and return) a HTTPResponse with correct content-type and write the PIL Image to the response.

Whenever you need to display a thumbnail flag, just use .

If (2), you could connect to Django's django.db.models.signals.post_save signal and in the signal handler create and save a thumbnail file.
