Should I take picture again when I apply for renewal of My EAD

yes

The I-765 form says that you have to send 2 photographs which are taken within the last 30 days ( and no older). It has to be 11/2 inch by 1 1/2 inch in size and top of head to your chin should be about 1 1/4 inch and so on.

Read the form for details.
