How to get nice photos of my 18 month old?

My son is 18 months and every time I take him to get his picture made all he does is cry.. he doesnt like unfamiliar places/ people & only wants me to hold him. soon as i put him down he just cries. I really would love some nice photos of him, but i feel like im wasting money because all i get is pictures of him crying or mad. The photographers try there best but there is only so much u can do and once hes mad hes mad... Any tips or tricks that may help?
