I don't think there is one. There are only various help and test threads.
Your problem is a Flickr-specific one, as you linked to the Flickr pages in which your images are embedded rather than the images themselves. In Flickr, just right-click on an image and 'Copy image' if you use Firefox, then paste it into a post. If you don't get the 'Copy Image' option, choose one of the image sizes available and 'Copy image' from there.
You can't delete posts yet, as you need to be out of the Nursery for that, which should happen imminently (today or tomorrow), as you've reached three posts.
