trying to make my own designs up for my family tree in word,

i have made out a pattern by using 3 cm by 3 cm squares to put in one square .type text the name birth death of a person

then another square with a photo 

but for the parents the squares the same, but in between another same size squar, for a "marraige symbole",

i have a marraige symbole, but it is to large ,how can i make it smaller to fit in my square ,in windows photo gallery,or word

tried using, edit, resize, down to 160 x 160, but when i go to print, to see if its the right size ,it always comes out printing the same size ,large,

why is this, can you help please, is there another way i can do this ,and make my picture small,to fit

you see i plane to fit these squares on a coloured sheet of A4 paper ,add the marraige symbol,flower edging to make it look good,then scan it to my windows word,

add text in the squares ,add photos in other squares,

but i cant find away to resize my marraige symbols,please can you help,
