Apple Script to find where a flickr photo (or photos) selected in the finder comes from. See http://cogdogblog.com/2015/10/21/flickr-trickr/ I use FastScripts to run this sort of thing.

Find Flickr Photo.scpt

tell application "Finder"
	set files_ to selection
	repeat with file_ in files_
		set imgkind to (kind of file_)
		
		
		repeat 1 times
			set imgkind to (kind of file_)
			
			if (imgkind does not contain "Image") then
				exit repeat -- 1 times
			end if
			
			set filename to name of file_
			
			set AppleScript's text item delimiters to {"_"}
			set theid to first text item of filename as string
			
			do shell script ("open http://flickr.com/photo.gne?id=" & theid)
			get theid
		end repeat
	end repeat
end tell
