Went to the settings of the Flickr App and Auto-Upload is not on, but I have a bunch of pictures, formerly taken, that I want to delete, can't figure out how to get rid of them.

I deleted them via my PC.
I try to always turn off any auto-upload setting in a photo app and it had been turned off in Flickr, but apparently, a while back I must have not turned it off - many apps have the auto uploading as default when you install them.
