Do I need photographs for each family member to extend a 60-day tourist visa in Thailand, and when does the extension start?

Hi all, quick question,

We need to extend our 60 day tourist visa - do we need fotos of each family member?

And will we get the Extension from the day we go to immigration or do they add them from the day our visa expires? ( that would be Monday, but we want to make sure we have everything at hand and would prefer to go end of this week, in case we missed anything then we could still go back on Monday)
