PHP strings connect to Image

I have a php file that reads data from mysql database. Can i link from string example: Id:1, Name: Ivan, Ivan="image source"? So can i link a string to a image source in my php, so i can use both data and picture in android studio?

this is my table:

{  
   "Grad":[  
      {  
         "id":null,
         "datum":"29.03.2015",
         "grad":"Pula",
         "place":"Zen",
         "adresa":"Zaobilaznica 3",
         "Dogadaj":"Narodna glazba i DJ Koprena",
         "Cijena":"Besplatno"
      },
      {  
         "id":null,
         "datum":"29.03.2015",
         "grad":"Pula",
         "place":"Pietas",
         "adresa":"Riva 13",
         "Dogadaj":"Narodna Glazba i Dj Sale",
         "Cijena":"Besplatno"
      },
      {  
         "id":null,
         "datum":"29.03.2015",
         "grad":"Pula",
         "place":"Uljanik",
         "adresa":"Monte Zaro 11",
         "Dogadaj":"Rostiljarka",
         "Cijena":"10 kn i pivo gratis"
      },
      {  
         "id":null,
         "datum":"29.03.2015",
         "grad":"Zminj",
         "place":"The Bar Zminj",
         "adresa":"Ulica Bartulja 2",
         "Dogadaj":"Night Express Band",
         "Cijena":"30kn"
      }
   ],
   "success":1
}

So i want to put for string place: Zen i want to display image from Zen folder, image Zen.jpg.
