to kng,
i just made my driving license, here are the photo requirements:
1) 3.5cm width
2) 4.5cm height w/o borders
3) taken less than 3 months ago
4) full face, image of face btwn 2.5cm and 3.5cm frm chin to crown of head
5) background screen must be white, unless your hair is white, then screen must be light grey
6) color, with matt or semi-matt finish
7) no headgear unless u habitually wear one
actually i took mine at the driving centre, the printout was on stg like thick paper, but i think better print a proper photo to be safe
wth... was typing according to the handout, then found this last line saying the above info can be obtained from "FAQS FOR PHOTOCARD LICENSE" at
