Fixes for listing 5.3 in Chapter 5.

Just a minor bug - should be evident in the changeset.

Also, I took the liberty of:

* making sure the "gallery" text for Fuji-X100 doesn't overflow into the adjacent product
* making sure that the product icons appear; previously they weren't

I haven't read through the chapter on testing yet, so I'm wondering if the tests are passing. Could you let me know how to check them?
