One more minor correction for LP Reorg

Hey Rich,

Two images are incorrectly displayed in the learning paths directory resulting from the learning paths reorg. This pull request removes them. I had resolved this merge conflict a couple days ago and added those photos into their new dir within the `mvc` dir. Somehow, the old photos still managed to stay in the incorrect dir. 

Long story short: the two photos are correctly placed, but their two old copies should be removed. I've done that in the first commit below. The second commit resolves just a couple link problems in our tutorials.

Thanks!
