The Library View Options determine
how photos look in the Grid view. You can specify different combinations
of elements, ranging from showing only thumbnails, to thumbnails
accompanied with photo information, filters, and Rotation buttons.
In the Library module, choose View >
View Options.
In the Grid View tab of the Library View Options dialog
box, select Show Grid Extras to view information and icons in the
photo thumbnail cells. (Show Grid Extras is selected by default.)
Deselecting this option shows photo thumbnails with no
additional information in the Grid view.
In the Options area of the dialog box, select any of
the following items:
Show Clickable Items
On Mouse Over Only
Shows clickable items, such as Rotation buttons and flags,
only when the pointer moves over the cell. Deselecting this option
means clickable items are always displayed.
Tint Grid Cells With Color Labels
Displays the label colors in the background of each cell.
Show Tooltips
Displays a description of an item, such as a photo, badge,
or pick flag, when you hold the mouse pointer over the item.
In the Cell Icons area of the dialog box, select any
of the following items to appear in expanded cells:
Pick Flags
Makes Pick or Rejected flags available in the upper left
corner of the thumbnail cell.
Quick Collection Markers
Shows the Quick Collection marker in the upper right
corner of the photo thumbnail.
Thumbnail Badges
Shows thumbnail badges indicating which photos have keywords,
cropping applied, or image adjustments.
Unsaved Metadata
When you’ve added metadata or metadata keywords to a
photo in Lightroom without saving the metadata to file, a down arrow
icon appears
in the upper right corner of the cell area. If you’ve added metadata
to a file in both Lightroom and a different application, such as
Adobe Bridge, an exclamation mark indicates
that metadata has been saved to the file in an external application.
In the Compact Cell Extras area, select any of the following
to appear in compact cells:
Index Number
Shows the order number of the photo in the Grid view.
Rotation
Makes Rotation buttons available.

Bottom Label

to appear in expanded cells:

Shows the header area of the thumbnail cell. The header
area can display up to four labels that you choose from the menus.
Show Footer
Shows the footer items you select.
Use Defaults
Restores the Grid view options to their factory-set defaults.
From the Show Grid Extras menu, choose one of the following to
set the size of the thumbnail cells in the Grid view:
Expanded Cells
Displays the most photo information available in the
Grid view, including filters, metadata, Quick Collection marks,
index numbers, and Rotation buttons.
Compact Cells
Display smaller cells with less photo information so
that more thumbnails are visible in the Grid view.
You can quickly change the Grid view options by choosing
from the Grid View Style menu. The views are based on the default
or custom view options set in the Library View Options.
In the Grid view, choose View > Grid
