Facebook FQL API for Photos states the maximum resolution for a photo returned from the API is 960x960:
The Photo object has an equivalent src connection. Using photo_src FQL, you can retrieve images with the following dimensions: 960, 720, 480, 320, 180, 130, 75 pixels.
However, some images are uploaded at a higher resolution. Sometimes even much higher.
When browsing Facebook regularly, you can see these pictures and view their full size. However, I can't seem to find any way to get the original resolution in the API.
Is this possible and I have missed something? And if it's not - why?
/USER_ID?fields=images
images gives back "an array of objects containing width, height, source each representing the various photo sizes". The result looks like this:
{
"data": [
{
"images": [
{
"height": 1536,
"width": 2048,
"source": "https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-prn1/s2048x2048/65169_XXXXXX_n.jpg"
},
{
"height": 720,
"width": 960,
"source": "https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-prn1/65169_44590146XXXXXXXXn.jpg"
},
{
"height": 540,
"width": 720,
"source": "https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-prn1/s720x720/65169_44XXXXXXX0984540_n.jpg"
},
{
...
},
{
"height": 97,
"width": 130,
"source": "https://fbcdn-photos-a.akamaihd.net/hphotos-ak-prn1/s75x225/65169_44XXXXX_s.jpg"
}
],
}
]
}
Try with more than 960, i.e 961. You'll get the maximum size of the picture, if available!
/USER_ID?fields=picture.height(961)
Result:
{
"id": "PROFILE_ID",
"picture": {
"data": {
"url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn1/615962_4486XXXXXXXXX3_601495975_o.jpg",
"width": 1536,
"height": 2048,
"is_silhouette": false
}
}
}
