Tiled, Centered and Restore � With the wallpaper shortcut added to the toolbar, press the drop-down arrow next the wallpaper icon and choose between Centered, Tiled, and Restore (as seen above). Alternatively, go to [Tools | Set Wallpaper | Restore]. � Holding down <Shift> when you click the wallpaper shortcut button is another way to have the wallpaper tiled (rather than centered). Or, select the corresponding command from the [Tools | Set Wallpaper] menu.

If the image is larger than the screen, it will be shrunk to fit. In View mode, you can set the desktop wallpaper to part of an image by selecting the region of interest before invoking the wallpaper command.

Thumbnails
When browsing, you can view images as thumbnails by selecting [View | Thumbnails] from the menu. ACDSee generates and displays a thumbnail for each of the images in the current folder. You can set the size of the thumbnail using preferences on the Thumbnails options page.

Thumbnail Caching
Because thumbnail generation can be a time-consuming process, ACDSee provides a thumbnail caching feature. Whenever a thumbnail is generated for a source image, it is saved in a central database file. The next time ACDSee requires the thumbnail for that image, it can read the thumbnail directly from the database file rather than decoding the source image again. This greatly enhances the speed at which ACDSee gathers thumbnails. See Customizing Using Options . You can choose to compress the thumbnails stored in the cache by going to [Tools | Options | Miscellaneous]. This saves disk space, but it often requires more time to read the thumbnails back in. In addition, if you choose a compression option other than [None] or [Lossless], the thumbnails� quality is noticeably degraded. By default, ACDSee stores thumbnails with no compression. ACDSee also caches thumbnails for image files on read-only and removable disks. ACDSee uses the volume label of a removable disk to identify it. Therefore, you can have several disks of images, possibly with the same names, and ACDSee still caches the images on each disk correctly and without conflict. If you modify an image whose thumbnail is cached, ACDSee automatically detects the change and regenerates the thumbnail the next time it is displayed. When you delete image files with ACDSee, the corresponding thumbnails are removed from the database to reclaim the space used.
