-(IBAction) selectimage
{
UIImagePickerController *picker=[[UIImagePickerController alloc] init];
picker.delegate=self;
picker.sourceType=UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController:picker animated:YES];
[picker release];
}
-(void) imagePickerController:(UIImagePickerController *)UIPicker didFinishPickingMediaWithInfo:(NSDictionary *) info
{
[UIPicker dismissModalViewControllerAnimated:YES];
imageview.image=[info objectForKey:"UIImagePickerControllerOriginalImage"];
    NSLog("Image Path=%@",imageview.image);
}

UIImagePickerControllerOriginalImage returns only the image's data, with no reference to its local storage. I haven't used it myself but I guess what you are looking for is

NSURL* localUrl = (NSURL *)[info valueForKey:UIImagePickerControllerReferenceURL];

At least, it's the only way I know of to retrieve any URL.

To retrieve the image, have a look at this question. But also keep in mind, that you already have the image retrieved with

UIImage* image=(UIImage*)[info objectForKey:@"UIImagePickerControllerOriginalImage"];

so ask yourself if you really need this.
