Flickr via NextGEN

I’ve been ‘google-ing’ this question for a few days now. I’ve seen this asked many times (over the past 5+ years) but have not seen any direct answers/solutions.

Here’s my issue:
1) I don’t want photos on our website taking up disk space on our hosting account.
2) We use Flickr for image storage/retrieval rather than posting them on Facebook and NextGen.
3) Our custom theme requires using NextGen.

So, with those parameters in mind…

I want to create a NextGen GALLERY and have it “full” of Flickr album images.

Is this possible?

Thanks.
