Lol NJ I have some spare ones as well Barsel. Depending on what purpose you need it for, authorising agency will see if it is a valid image of you. Happy photo copying.
When you right-click an image in Word, there should be a sizing dialogue in a little box, all to itself, above the larger one which has 'Cut', 'copy, 'Paste options'. Use that upper box to change the height to 4.5cm.
OR . . .
After right-clicking, select 'Size and Position' and change the height there.
(That's based upon Word 2010. It should be roughly similar in all other versions of Word and, indeed, with all other word processors).
Thanks Chris, I had a play around with it and managed to resize it. I have Word 2007 so it's a bit different but it's now the right size for printing. Just got to look for my photo paper now.
Thanks to all for your input. x
