First, download all OSM objects that contain the substring “imgur” inside the “image:” tag. I use Overpass API on JOSM.

[out:xml][timeout:90];
(
  nwr[~"image"~"https://i.imgur.*"];
);
(._;>;);
out meta;

Then, export the downloaded OSM objects as GeoJSON file for further processing.

Next, for the sake of simplicity, filter everything except OSM point node. Also trim all of the OSM tag except the image to minimize the GeoJSON filesize.

import json
f = open('imgur.json',encoding='utf-8')
data = json.load(f)
allobj = data['features']
newdata = {}
newdata['type'] = "FeatureCollection"
newdata['generator'] = "rtnf"
newdata['features'] = []

for i in allobj:
	if i['geometry']['type'] == "Point":
		prop = i['properties']
		for j in prop:
			if "image" in j:
				#print(prop[j])
				newy = {}
				newy['type'] = "Feature"
				newy['properties'] = {}
				newy['properties']['image'] = prop[j]
				newy['geometry'] = i['geometry']
				newdata['features'].append(newy)
print(json.dumps(newdata))

Finally, show this preprocessed geojson file by using Leaflet frontend. Since the dataset is quite massive, use MarkerCluster plugin. I tried it before without this plugin, and my browser was crashed.

var map = L.map('mapid',{ preferCanvas:true, zoomControl: false }).setView({lat: -6.2, lng:  107.0},1)

// Basemap
L.tileLayer(
  'https://tile.tracestrack.com/_/{z}/{x}/{y}.png', {
    maxZoom: 18,
    attribution: 'Data: © <a href="https://www.openstreetmap.org/copyright">OpenStreetMap contributors</a>
  }).addTo(map);

// Marker cluster
var markers = L.markerClusterGroup();
markers.addLayer(L.geoJSON(a, {
    onEachFeature: onEachFeature
}));
map.addLayer(markers)

// Pop-up on click
function onEachFeature(feature, layer) {
    if (feature.properties && feature.properties.image) {
        layer.bindPopup("<img src='"+feature.properties.image+"'><br><a target='_blank' href='"+feature.properties.image+"'>Image license</a>");
    }
}
