@polkadotcreations not yet I’m afraid. I’ll post back here if I do. My best guess is that Flickr detects the browser identification, or something else to detect web crawlers, and doesn’t serve images back to requests it thinks aren’t interactive web users… So possibly whichever method of requesting used by this plugin doesn’t look enough like an interactive user.
My Flickr account rolls around again in a few months so I might have another look then, but am away from home right now. Maybe there’s an edit to the plugin code that could make it look more like a normal web browser as far as Flickr is concerned.
