When I saw John’s script for building an image browser in Drummer from Flickr photos I figured it should be possible to use the PublicFolder JSON log as a source.

Ofcourse it is. I used the JSON.parse scripting to get every node. Build some checks to see if the uploaded image has an URL. See screenshot below

You can copy and play around with the script on this public Gist at Github. Have fun and let me know when you expand it with new possibilities!
