flickr photobar - get description - photo

Question

I implemented this jquery http://tympanus.net/Tutorials/FlickrPhotobarGallery/ and I can capture setname and title but I need to get description too, so I would like to know if this is possible.
Hope someone can help me, thanks in advance!

If you want the description of a set you can call flickr.photosets.getInfo.
On an unrelated note, you can save an API call to flickr.photos.getSizes for each photo in the set by passing in an extras parameter specifying all of the urls you'd like to get back when calling flickr.photosets.getPhotos. For any size identifier (sq, t, m, l, o, etc.), just pass in an extra of url_(identifier) (so, url_o would have the response contain the original url if it was available). This is documented here: http://www.flickr.com/services/api/flickr.photosets.getPhotos.html
