sharing image using FBGraph API is not working

I have used the below code to share an image on fb wall:

NSData *imageData = UIImageJPEGRepresentation(self.selectedImage, 10);
NSMutableDictionary* variables = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"your caption message", @"message", imageData, @"data", nil];
FbGraphResponse *fb_graph_response = [[sharedSingleton fbGraph] doGraphPost:@"me/photos" withPostVars:variables];
NSLog(@"postMeFeedButtonPressed:  %@", fb_graph_response.htmlResponse);

but the app is getting crashed when ever I try to share. Guide me to solve this issue

Try This Code.....

-(IBAction)postPictureButtonPressed:(id)sender {

NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:2];

//create a UIImage (you could use the picture album or camera too)
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 20, 240, 240)];
[imgView setImage:[UIImage imageNamed:@"app1.jpg"]];
[self.view addSubview:imgView];
[imgView release];


UIImage *tempimag=imgView.image;

//UIImage *picture = [UIImage imageNamed:@"75x75.png"];

//create a FbGraphFile object insance and set the picture we wish to publish on it
FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:tempimag];

NSLog(@"img posted");


//finally, set the FbGraphFileobject onto our variables dictionary....
[variables setObject:graph_file forKey:@"file"];

[variables setObject:@"this is a test message: postPictureButtonPressed" forKey:@"message"];

//the fbGraph object is smart enough to recognize the binary image data inside the FbGraphFile
//object and treat that is such.....
FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"117795728310/photos" withPostVars:variables];
NSLog(@"postPictureButtonPressed:  %@", fb_graph_response.htmlResponse);


NSLog(@"Now log into Facebook and look at your profile & photo albums...");

}
