How to get the bigger profile picture of a faceboo

Question

I am getting an image from facebook by the URL: http://external.ak.fbcdn.net/safe_image.php?d=d282e1e7c86c9270232f97ddc737df39&w=90&h=90&url=http%3A%2F%2Fi52.tinypic.com%2F2q0ixzl.jpg

Now, I want a bigger version, like 200 by 200. Is there a URL for that? If not, how can I convert this image to a larger size?

Answer 1

Generally if you want to collect the profile pic of a user or page, the format for the icon size picture is:

http://graph.facebook.com/[page id/profile id]/picture

and for the large picture:

http://graph.facebook.com/[page id/profile id]/picture?type=large

EDIT Points to note: If the image stored on the facebook servers is less than the 200*200 dimensions, you would get the image as the highest resolution avaiable eg: 128*160. Either you can resize it using the GD library.

AND ONE MORE THING

Facebook supports 200*600px as the highest resolution for the profile pic. It will resize an image to fit into these dimensions by maintaining the aspect ratio.

*UPDATE as on 19th Feb, 2017 *

We need to use this new URL formation to get a desired profile image.

http://graph.facebook.com/{profile_id}/picture?width={number‌​}&height={number}

Answer 2

If you want to get a larger picture you can just set the height and width you want like this:

http://graph.facebook.com/[page id/profile id]/picture?width=[number]&height=[number]

this will also work

picture.type(large)

example

 if ([FBSDKAccessToken currentAccessToken]) {
    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"picture.type(large),name, email"}]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
         if (!error) {
             NSLog(@"fetched user:%@", result);
             NSMutableDictionary *data=[[NSMutableDictionary alloc]init];
             data=result;


             fbId.text=[data valueForKey:@"id"];
             userName.text=[data valueForKey:@"name"];
             _emailFB.text=[data valueForKey:@"email"];



             NSDictionary *dictionary = (NSDictionary *)result;

             NSDictionary *data3 = [dictionary objectForKey:@"picture"];
             NSDictionary *data2 = [data3 objectForKey:@"data"];
             NSString *photoUrl = (NSString *)[data2 objectForKey:@"url"];

             NSLog(@"Photo : %@",photoUrl);


         }
     }];
}

}

YES, there is a way to get the original (most of time bigger) profile picture of a facebook page.

Actually the answer is already in the question. The original image url is already embedded in the save_image url. In your case it is "url=http%3A%2F%2Fi52.tinypic.com%2F2q0ixzl.jpg” which means "http://i52.tinypic.com/2q0ixzl.jpg"

In my case, the page for London is

https://www.facebook.com/pages/London-United-Kingdom/106078429431815?fref=ts

I can easily get its fb object id by search keyword London. I have tried to use width and height parameter. They work with user profile picture or user shared picture but can’t work with public pages profile picture.

https://graph.facebook.com/106078429431815/picture?width=300&height=300  // can’t work

The largest picture I can get it by following url which is only 180x77

https://graph.facebook.com/106078429431815/picture?type=large

But I can get safe_image.php url by using fb graph api, and the original image url is also inside the parameters' url section

"url": "https://fbexternal-a.akamaihd.net/safe_image.php?d=AQCrtKykRotXBuaS&w=180&h=540&url=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fthumb%2Farchive%2F2%2F21%2F20141005220235%2521City_of_London_skyline_at_dusk.jpg%2F720px-City_of_London_skyline_at_dusk.jpg&fallback=hub_city&prefix=d"

Here is code I used.

[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"/%@/picture?redirect=false&type=large",[firstCityPage objectForKey:@"id"]]
                    completionHandler:^(
                                        FBRequestConnection *connection,
                                        id result,
                                        NSError *error
                                        ) {

                        NSString *profileImgUrl = [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large", [firstCityPage objectForKey:@"id"]];

                        if (error==nil) {
                            NSString *fbSaveImgUrl = [[(NSDictionary*)result objectForKey:@"data"] objectForKey:@"url"];

                            NSURLComponents *urlComponents = [NSURLComponents componentsWithURL:[NSURL URLWithString:fbSaveImgUrl]
                                                                        resolvingAgainstBaseURL:NO];

                            for (NSURLQueryItem *queryItem in urlComponents.queryItems) {
                                if ([queryItem.name isEqualToString:@"url"]) {
                                    profileImgUrl = queryItem.value;
                                    break;
                                }
                            }

                        } else {
                            NSLog(@"%@",[error description]);
                        }

                        NSLog(@"url: %@", profileImgUrl);

                        ...
                    }];

BUT, there are risks.

1. No guarantee the external image url will be validate.

2. Facebook may remove the explicit external url in the safe_image url or hide the safe_image url from developer in future.

Use it at your own risk.
