getting high resolution photos that were posted on a page wall/feed - facebook-graph-api

Question

I'm getting my page wall with the open graph.
And when someone posted a photo, I get it on the JSON
{
"id": "27888702146_10150369820322147",
"from": {
"name": "brocoli",
"category": "Record label",
"id": "27888702146"
},
"message": "Vincent Epplay / David Fenech / Jac Berrocal \u00e0 Beaubourg ce soir, 19h, gratos.",
"picture": "http://photos-f.ak.fbcdn.net/hphotos-ak-snc7/305819_10150369820292147_27888702146_8255527_583491475_s.jpg",
"link": "https://www.facebook.com/photo.php?fbid=10150369820292147&set=a.386279807146.165840.27888702146&type=1",
"icon": "http://static.ak.fbcdn.net/rsrc.php/v1/yz/r/StEh3RhPvjk.gif",
"type": "photo",
"object_id": "10150369820292147",
"created_time": "2011-10-16T08:22:21+0000",
"updated_time": "2011-10-16T08:22:21+0000",
"likes": {
"data": [
{
"name": "brocoli",
"category": "Record label",
"id": "27888702146"
},
{
"name": "Agathe Morier",
"id": "601668526"
}
],
"count": 2
},
"comments": {
"count": 0
},
"is_published": true
}
The problem is that the picture link is a low resolution copy of the picture.
How can I get the URL of the full picture ?
Thanks!!

Answer 1

You can get different version of the photo by querying Graph API with its object_id (not photo post_id which is id in results you provided).
Once you'll request the photo by object id you'll get array of images with URLs and dimensions:
http://graph.facebook.com/10150369820292147?fields=images
If you're attempting to access posts on a Facebook Page (such as for a company) instead of typical user profile, you firstly need to fetch the feed like this:
https://graph.facebook.com/v15.0/YOUR_PAGE_ID_HERE/feed?fields=attachments&access_token=...
And then access data[0].attachments.data[0].subattachments.data[0].target.id to get the object ID (or "target ID" in this case) which you can then use to perform an additional query to obtain the higher resolution image. Increment the numbers to get additional posts and images inside each post.

Answer 2

All you need to do is :
http://graph.facebook.com/me?fields=picture.height(961)
// replace 961 with your required height which u want

Answer 3

You can do this from the main posts list now using
/v2.3/105753476132681/posts?limit=5&fields=likes.summary(true),comments.summary(true), attachments
If attachments doesn't work, try full_picture - but that just gave the 100x100 image for me as well.
Attachments returns a data hash with a 640x480 version of the image at least (not sure what my orig. photo size was)

Answer 4

Use this Code. Its Work for me and get Clear Image
String PICTURE_URL;
String getPicture = hashMap.get("picture");
if (getPicture.contains("_t.")) {
PICTURE_URL = getPicture.replaceAll("_t.", "_n.");
} else if (getPicture.contains("_a.")) {
PICTURE_URL = getPicture.replaceAll("_a.", "_n.");
} else if (getPicture.contains("_s.")) {
PICTURE_URL = getPicture.replaceAll("_s.", "_n.");
} else if (getPicture.contains("_q.")) {
PICTURE_URL = getPicture.replaceAll("_q.", "_n.");
}
url=new URL(PICTURE_URL);
Bitmap bitmap=BitmapFactory.decodeStream(url.openConnection().getInputStream());
((ImageView)view.findViewById(R.id.imageView_FullImage)).setImageBitmap(bitmap);

Answer 5

Though requesting a photo by its object_id will return an array of images with different dimensions, in some cases this approach would require an additional call to the Facebook API.
A simpler approach is to add full_picture to your list of parameters, which will extract the highest resolution image associated with the post.
/v2.2/6275848869/posts?fields=full_picture
For example, if you want to extract all the posts from a Facebook page in the past X days, with the object_id approach you'd need to call the API 3 times:
To get the page info.
To extract the list of posts and obtain the object_id for each post.
For each object_id, to retrieve the list of higher resolution images.
