"View" Dropdown does not include "Thumbnails"

[self]

Something has gone wrong with my explorer I can no longer see thumbnails
of my photos:

My problem:
My explorer toolbar shows "file edit view tools help".

When I click on "view"
The ONLY choices I get are:
Extra large icons
large icons
medium icons
small icons
list
detail
tiles

But there is no "thumbnails" to select.

Possible clues:
A toolbar i never saw before has appeared and it has on it "Organize"
"Views" and "Burn"
When I click on "Views" on that toolbar I get the same selection as when
I click on "View" on the mail toolbar.
Thanks

In Vista, "thumbnails" is not an option on that menu. The small medium and
large icons are the thumbnails and you can choose by size.

To make sure thumbnails are enabled, goto Start > Control Panel > Folder
Options

Click the View tab. Make sure the "Always show icons, never thumbnails" is
not selected.
