display different image of each node on mobile suite example of d3 - d3.js

Question

How to display each node of different image. I show an example of d3 on github. but in this there is only one links.
How to display each node a different image. Any solution?
This is my example.
var nodes = {};
// Compute the distinct nodes from the links.
links.forEach(function(link) {
link.source = nodes[link.source] || (nodes[link.source] = {name: link.source});
link.target = nodes[link.target] || (nodes[link.target] = {name: link.target});
});
var width = 900,
height = 900;
var force = d3.layout.force()
.nodes(d3.values(nodes))
.links(links)
.size([width, height])
.linkDistance(90)
.charge(-600)
.on("tick", tick)
.start(type, crawledPageID);
var svg = d3.select("#d3Graph").append("svg")
.attr("width", width)
.attr("height", height).call(zoom);
// Per-type markers, as they don't inherit styles.
svg.append("defs").selectAll("marker")
.data(["suit", "licensing", "resolved"])
.enter().append("marker")
.attr("id", function(d) { return d; })
.attr("viewBox", "0 -5 10 10")
.attr("refX", 15)
.attr("refY", -1.5)
.attr("markerWidth", 6)
.attr("markerHeight", 6)
.attr("orient", "auto")
.append("path")
.attr("d", "M0,-5L10,0L0,5");
var path = svg.append("g").selectAll("path")
.data(force.links())
.enter().append("path")
.attr("class", function(d) { return "link " + d.type; })
.attr("marker-end", function(d) { return "url(#" + d.type + ")"; });
var circle = svg.append("g").selectAll("circle")
.data(force.nodes())
.enter().append("circle")
.attr("r", 3)
.call(force.drag);
var text = svg.append("g").selectAll("text")
.data(force.nodes())
.enter().append("text")
.attr("x", 6)
.attr("y", ".21em")
.text(function(d) {return d.name; });
var edgeText = svg.append("svg:g").selectAll("path")
.data(force.links())
.enter().append("svg:path")
.attr("id", function(d) { return d.source.index + "_" + d.target.index; })
.attr("class", function(d) { return "link " + d.type; })
.attr("marker-end", function(d) { return "url(#" + d.type + ")"; });
var path_label = svg.append("svg:g").selectAll(".path_label")
.data(force.links())
.enter().append("svg:text")
.attr("class", "path_label")
.append("svg:textPath")
.attr("startOffset", "50%")
.attr("text-anchor", "middle")
.attr("xlink:href", function(d) { return "#" + d.source.index + "_" + d.target.index; })
.style("fill", "#000")//edge color
.style("font-size","10px")
.style("font-family", "Serif")
.text(function displayNote(d){ return "";// d.rel;
});
/**

var chkStatus1 = document.getElementById("door2");
if (chkStatus1.checked)
{
return d.rel;
}
else
{
return "----";
}
