Updated README for move of images to bssw.io/images/ directory (#738)

More specifically, and in addition I did the following:

* Updated instructions for uploading an image to just treating it like a regular file in the repo under the images/ directory

* Replaced references to the separate github images repo to local images/ directory path

* Added vertical white-space to make the document structure easier to see while editing

* Fixed some misspellings and other typos

* Adding more formatting for literals like `.jpgs`

* Removed some extra trailing white-space

* Added some missing punctuation where needed

* Added temp note at the top that the transtion is still in progress
