Passport photos

My roommate is in need of passport photos but is unsure of where to get them from. Please help. An instant passport photo booth would be great.

I've never seen an instant passport photo booth in Riyadh.  But then, I've never been looking. 

There is a photo shop at Jazeera Souq, on Mujashi ibn Masud St.  That's where I  had my PP photo's taken.   It was relatively quick.  I can only presume there are other such shops around the city if that one is too far from your residence.

Go to any photo studio.  There are many of them all over the place.  They will take your picture and give you prints in whatever form or shape you want.  Get a copy of the digital picture as well - take a USB with you; helps in times of future needs.
