Next up: the user should be able to delete a picture.
Added navigation links for each picture in the list of all pictures; one to show the details of the picture, one to edit the picture, and one to delete the picture.
Defined a method to handle the delete a picture request.
Wrote some logic to load up the row from the table, destroy it, and redirect the user to the list of all pictures.
Fixed a typo in the routes file, and now we're done with our RESTful CRUD resource. Congrats :)
