US passport photos?

Hello, I need to get some photos taken of me for my US passport renewal and was wondering if any of you expats know where in  Odessa I can get the correctly sized photos? It appears that the photos need be the right size (51 x 51mm) and I am concerned I will take the wrong photo sizes. Let me know as I will appreciate it.

I just need the name and address of the business.

Thank you
