Tier 1 (general) forgot to post Photographs

Hi
recently I sent Tier-I application but I forgot to include photographs, What should I do now, can I post them now or shall I wait till they ask me

Thank you in advance

fill out change of circumstances fom and send it away. dont forget to write your name on back of pics.

write covering letter as well and give your name, date of birth, passport number, and nationality details on covering letter

regards
