Hi Seeker, 
If you were applying in Europe it would depend entirely up to you. But since Dubai is an image orientated city (for what I've been advised) you should definately endorse a photo with you Curriculum Vitae.
 
 
 
I am not so keen on this, however, as skills could often be forgotten or left on the side for appearence. 
 
 
All the best in your hunt!
