hmmm. mine were pasted sa bond paper. about 4 photos sa isang bond paper without descriptions sa likod ng mga photos but with captions sa bawat paper na may photos kung ano yung mga litratong yun (i.e wedding ceremony, reception, out of town trip photos etc. etc.). so far wala naman problema. when CEM sent me a passport request, they didn't ask for additional proofs sa relationship so i believe what i did was fine with them. As long as your application is pretty straightforward without rooms for them to doubt your authenticity, genuineness, truthfulness and what not with regard to your relationship with your spouse, someone whose on the same boat will be just fine.
