guarantor/notarization

[TJL]

My wife and I had our immigration photos taken while in Canada for a visit just recently.  We're trying to get them properly "certified".  Is there a document we need in order to accomplish this?  Who can sign the photos?  Do we need a document for the guarantor to complete?
Thanks

You don't need to certify your pictures.  If they don't look like the people in your passports, then you'll run into problems.

You can write your names on the back.  Use an indelible ink that won't smudge onto the other pictures.
