You'd need to split out the value from the keyword, then set up a dict using the keyword as the key, and the value as the value. You could then use the double-asterisk function paramater with the dict.

So...

keyword, sep, value = f.partition('=')
kwargs = {keyword: value.strip('"')}
d = Image.objects.filter(**kwargs)

Note, this code assumes that there won't be any equals signs '=' in the keyword (they'll only be used to separate the keyword from the value), and the value will be wrapped in quotes.
