His photos will illustrate how to sex veiled chameleons easily, even as babies. This will apply in over 90% of all cases; there is always the odd chameleon that is a female with large spurs or a male with little ones, but by and large this method is a great way to identify a chameleon as male or female before any of the adult coloration comes in.
As adults identification should be easy; the male sports an impressive casque, has bright vertical bands of color, and has the thick tail-base typical of male chameleons where they hide their hemipenes. Females should be overall smaller, with smaller casques, typically solid green with speckles of color instead of bands, and a narrow tail base. In addition to this, males will have what are known as spurs on the back of their hind feet; a little protuberance like the spur on a cowboy's heel. Something (most) females do not have. The spur is present at the moment of hatchling, so even a newly-minted baby chameleon should be sexable this way with good certainty.
