One of the ways is to convert the geotagged photos in a Flickr album to KML, A quick Google search turned up a post at AdamFranco.com - Flickr Photo Set to KML. Click Photo Set to KML in the post to open the web utility.
First put the desired geotagged photos into a Flickr Album (formerly a Flickr Set). Next, open the album and obtain the album ID from the URL:
Copy the album ID and paste it into the KML utility, then click Submit:
The KML will be processed, and downloaded. Once downloaded you can add it to your ArcGIS Online account, then add it to a web map. You can also use the KML in Google Maps, Google Earth, ArcGIS Earth, or any other application that supports KML.
