关于图表Api的Facebook页面/组馈送的帖子图片大小

Question

I am displaying feed/posts of facebook page/group via graph api in my site by calling this Url in php code -

https://graph.facebook.com/page_id/feed?access_token=token_value

Then, Among many type of posts, for a post of picture type i get picture url as

http://photos-g.ak.fbcdn.net/hphotos-ak-frc3/t1.0-0/1972372_10152261154160659_883879121_s.jpg

Now it's the small size as the last part "_s.jpg" indicates.But i want all picture sizes be large.So to achieve this what parameters are needed to include in the graph api url - "https://graph.facebook.com/page_id/feed?access_token=token_value" so that all picture/video type of posts' picture will be in large size??, so is there will be "_b.jpg" at last as i presume.Is that possible in one graph api call?

I searched through the google but no luck, but ended up planning that i would replace the last part of the pic url above with "_b.jpg" so that url will be like -

http://photos-g.ak.fbcdn.net/hphotos-ak-frc3/t1.0-0/1972372_10152261154160659_883879121_b.jpg

But are there any drawbacks for this hack?? what are the correct ways to achieve if possible in one graph api call.

You could use a FQL query to get the source info of the large versions of the photos use in a Page's feed:

SELECT pid, object_id, src_big, src_big_width, src_big_height FROM photo WHERE object_id in (SELECT attachment.media.photo.fbid FROM stream WHERE source_id={page_id} AND actor_id={page_id})
