When you delete your Flickr photos which were published from iPhoto, they will no longer appear on your Flickr, but will remain in your iPhoto library. Here's how you delete published iPhotos photo albums from Flickr
- Click your Flickr account in the Source list. The Source list appears along the left side of the iPhoto window.
- To delete entire set/album, select it and then press Command-Delete. However, if you want photos to remain in your Flickr photostream, Click 'Delete Set'. Otherwise, click 'Delete Set and Photos' to delete the entire set and remove the photos from your Flickr photostream.
- If you moved some photos to this set from within Flickr, iPhoto will ask if you want to import them into iPhoto before the set is deleted. Only web-sized versions are imported.
- If you want to delete some specific photos and not the entire set, open the set, select the photos and then press Delete key.
That's it this is how you delete photos published on Flickr.
