When my wife applied for her visa, we printed off 4 pictures to a page. Each page covered each trip I made to the Philippines so I just put the date at the top of the page of when the visit took place. I didn't bother to describe each picture individually.
When I went back the last time for our wedding, I had 4 pictures on a page of our time together in the Philippines, 4 on a page showing our wedding, and 4 on a page showing our honeymoon in HK.
Yam, got the spouse visa and she's been here with me in the UK for just over a year now! :-)
Good luck with your application.
