from the database aspect, you would need a column (of data type BLOB - in oracle, don't know if this applies for other databases) on one of your tables (perharps personInfo) that would hold the image information. I am not very conversant with Java, so i don't know how you would link that. You could google for more info regarding that.
As for the table, you would prob have something like this;
personID number, (pk)
phoneNo varchar2(30) //this can also be the pk since no two persons have the same phone no
