Here's some camels for you. The two on the left are taken from a graphics pack Harlan Thompson put out a while ago, and the two on the right are taken from Allard H.S. Höfelt's Riverwar scenario (which also has some very nice graphics of Arabs on horses).
BTW, my Great Grandad was in the Australian Light Horse division which served in Palistine in WW1.
The only words of wisdom he ever gave my mum were "never get on a camel - they're horrible bloody animals, and riding them does your back in"
