Redundant text.
"But we're not ready to run the migration until we've created our model objects and

On page 39, we create slideshow_data.sql. On page 46 it is refered to as
photos_data.sql.
Also on page 46, it doesn't specifically say that once the new data
is appended to the .sql file we need to do "rake migrate VERSION=0" and then "rake
migrate" again (because otherwise you end up inserting the same data over again).

The text instructs the reader to "look at one of the views. Open app/views/photos/list.rhtml..."
It then goes on to present the code from show.rhtml, not list.rhtml.
That should be replaced with the code from photos/list.rhtml.
Note that we should also change:
- the next paragraph should say tthe 'show' method
- the paragraph after the explanation should say show.rhtml
("...if we add more properties, the show.rhtml view won't require any modification to display
them.")

The 3 sections explaining the code end with colons and not periods. This is misleading
because they are referring to the code above them, not following them.
That is:
"You saw this line before in the photos list template. It loops through each database row
contained in @slideshows (which was set by the controller), assigning each, in turn, to
slideshow:"
should end with a period and not a colon.
Also:
"This div is simply a caption block that displays the name of the slideshow along with
the number of photos it contains:"
should end with a period and not a colon.
And:
"This div shows a little preview of the slideshow by displaying the thumbnails of the
first three photos in the slideshow:"
should end with a period and not a colon.
