If the photo is too big, meaning there is background not needed around myself, would UKBA cut those parts to make it as they would need it or are they more likely to not bother and refuse the photos straight away?

Thanks for your response
Will I be able to re-submit with no fees to be paid?
Also, will the application take less time than usual if it is only a problem of a photo?

I just sent my extension application and I am worried about my photograph.
Not only I have forgotten to write my name behind the photo but also the photo is a bit too big, meaning it is about 50mmx38mm.
will that affect my application or cause it to be denied?
thank you
