Adding Images to feature pop-up windows in Leaflet maps

Images, graphs and charts can be displayed within pop up displays in a leaflet map to enrich the information available to the end-user of the map.


First, we prepare the html webpage with a simple leaflet map and in the script section

we write the OnEachFeature function which assigns a bindPopup  to values in

the properties field –Name.


function onEachFeature(feature, layer){
if( {


Then we create a variable object- Cities- and load the geojson point features and insert the <img/> image tags into the property- Name.

The contents of the pop up window for each feature is highlighted in red.

Note the image urls within the img tags


var Cities = [{
“type”: “Feature”,
“properties”: {
“Name”: “<h4 style=’color:red’;>Capital City of Abuja</h4><br>Country: Nigeria<br>

<img src=’’ width=100 height=80 /><br>

The fast growing federal capital city of Africa most populous country.”
“geometry”: {
“type”: “Point”,
“coordinates”: [7.00, 9.00]
}}, {
“type”: “Feature”,
“properties”: {
“Name”: “<h4 style=’color:red’;>City of Ibadan</h4><br>Country: Nigeria<br>

<img src=’’ width=100 height=80 /><br>

The largest city in West africa in land area. An ancient city of note, once a military fortress.”
“geometry”: {
“type”: “Point”,
“coordinates”: [3.50, 7.50]
var style = {
fillColor: “yellow”,
color: “red”


Then we use the pointToLayer function to return the default markers as circular markers

and add to the map. The onEachFeature in the code binds the popup contents to

their respective geojson feature.


L.geoJson(Cities, {onEachFeature,
pointToLayer: function(feature, latlng) {
return L.circleMarker(latlng, style); }}


Click on the circular markers and the pop up displays the images.
