How to post photos to facebook iphone fbconnect

Hi I'm using FBConnect to post to facebook, now I need to post photos from library or taken with the cam, does anyone has a clue how to do this ?? I've searched in google but I can't find a piece of code that works for me. I've found this method:

FBRequest *uploadPhotoRequest = [FBRequest requestWithDelegate:self];
     [uploadPhotoRequest call:@"photos.upload" params:args];

but in my fbconnect i have this one instead: (I think the version of the api is different)

 [_fbRequest call:(NSString *) params:(NSDictionary *) dataParam:(NSData *)];

Also I'm using this method to post to the wall:

 - (void)postToWall {       FBStreamDialog* dialog = [[[FBStreamDialog
 alloc] init] autorelease];
 dialog.userMessagePrompt = @"Enter your message:";   
 dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@ Esta conectado desde TravelFan iPhone App\",\"caption\":\"Viajar te cambia la vida\",\"description\":\"\",\"media\":[{\"type\":\"image\",\"src\":\"http://www.travelfan.com.mx/content/templates/default/images/logo_travel.jpg\",\"href\":\"http://www.travelfan.com.mx/\"}]}",
 _facebookName];   
dialog.actionLinks = @"[{\"text\":\"Obten TravelFan
 App!\",\"href\":\"http://www.travelfan.com.mx/\"}]";   [dialog show];  
 }

In this method I can send an image but not as a photo its just for the app logo and its an attachment.

Can anyone tell how to post photos to the wall pls ?? Any help is apreciated XD.

Solution

You can now post photos on your wall with requestWithGraphPath method as follows.

NSData *yourImageData= UIImagePNGRepresentation(yourImage);

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"Your text with picture", @"message", yourImageData, @"source", nil];

[facebook requestWithGraphPath:@"/me/photos" andParams:params andHttpMethod:@"POST" andDelegate:self];
