how we can share images with Twitter/facebook

twitpic images expire after about 17 minutes--which means 17 minutes after scraping, users won't have access to the images.
So I use :

Plixi API Document :

Sample iPhone Code (Upload)

-(NSData*) UploadPlixi : (NSData*) imageData

{

      NSString *apikey = [self GetApiKey:self.mediaService];

      float piclongitude = 122;

      float piclatitude = 40;

      BOOL emptyMsg = (self.message==nil || [self.message length] == 0);

      NSString *uploadAndPost =  emptyMsg ? @"http://api.plixi.com/api/tpapi.svc/upload" : @"http://api.plixi.com/api/tpapi.svc/uploadandpost";

      NSString *twitter_password = [self.password copy];

      NSString *twitter_username = [self.userName copy];

      NSString *twitter_msg = @"Plixi API is awesome!";

     

      /*build XML like this, the Location & tags elements are optional everything else is required

       

      http://api.plixi.com" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">

                  lat

                  long

            

            give it the tweet message

            image/png

            password

            cat,cool,yes

            username

      

      */

     

      NSString *xml = [NSString stringWithFormat:@"http://api.plixi.com\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">%@%@%@%@%@%@%@",

            [NSString stringWithFormat:@"%@",apikey], //your developer apikey this is required

            [NSString stringWithFormat:@"%.6f%.6f",piclatitude,piclongitude],

            [NSString stringWithFormat:@"%@",twitter_msg], //message you want to tweet

            [NSString stringWithFormat:@"image/png"], //i'm using png in my code, change this to whatever you're using

            [NSString stringWithFormat:@"%@",twitter_password], //twitter password

            [NSString stringWithFormat:@"%@",@"tag1,tag2,tag3"], //comma seperated list of tags

            [NSString stringWithFormat:@"%@",twitter_username]]; //twitter user name

     

      //get UTF8Encoded XML String

      NSMutableData *uploadPostData = [NSMutableData data];

      [uploadPostData appendData:[xml dataUsingEncoding:NSUTF8StringEncoding]]; //write the XML as UTF8 encoded bytes first

      [uploadPostData appendData:[NSData dataWithData:imageData]]; //write the bytes that represent the image next

     

      //Create a post request

      NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

      [request setURL:[NSURL URLWithString:uploadAndPost]];

      [request setHTTPMethod:@"POST"];   

      [request addValue:@"application/x-www-form-urlencoded" forHTTPHeaderField: @"Content-Type"];    

      [request addValue:[NSString stringWithFormat:@"%d",[imageData length]] forHTTPHeaderField: @"TPAPIImageSize"];   //this is a custom header, tell the server what size the image is in bytes

      [request addValue:[NSString stringWithFormat:@"%d",[uploadPostData length]] forHTTPHeaderField: @"Content-Length"];   //this is the size of the entire message size in bytes, not sure if this is autoset

      [request setHTTPBody:uploadPostData];    

      //now send it away - slow code this is synchronous!

      return [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
