Q: simplest way to put photos on internet for TR

I'm confused. Three pics are allowed w/o use of a host site. Are we talking about more than that?
My question is now why won't the photos orient portrait and not just landscape?

Jake, I use Flickr to share my hiking photos with the folks who join me on hikes and for trip reports on WTA. It's easy to share a link to all photos for a particular trip. My approx 60,000 public photos have been viewed almost 7.5 million times now.
