UIImage display differently when saving and loading from file

I'm download jpeg picture from web server and load it to UIImage.

If I display the UIImage in UIImageView directly, I see the picture correctly.

But if i cache the image to file with : [UIImageJPEGRepresentation(image,1.0f) writeToFile:sFilePath atoimcally:YES] and load it with :

image=[UIImage imageWithContentsOFile:sFilePath]

and display this in the same UIImageView, I can see white stripes in the sides of the picture.

again, Exactly the same UIImageView object with the same properties settings in it.

Why is that?

You can simply write to a file the NSData you have loaded from the web, without going through the UIImageJPEGRepresentation routine. 

[dataObject writeToURL:fileURL atomically:YES];

and to retrieve

UIImage *image = [[UIImage alloc] initWithContentsOfFile:[fileURL path]];

That works really well in my app.
