'''Thumbnails''' are reduced-size versions of pictures, serving the same role for images as a normal text index does for words.
+
 
+
== [[Windows]] ==
+
 
+
See [[Thumbs.db]].
+
 
+
== [[Windows]] Vista ==
+
 
+
''See [[Vista thumbcache]]''
+
 
+
Thumbs.db no longer exists in Vista. This data has been moved to ''\Users\\AppData\Local\Microsoft\Windows\Explorer''
+
 
+
[[Windows]] Vista will save thumbnails for files on mounted encrypted file systems (except [[Windows Encrypted File System | EFS]]).
+
 
+
== KDE & GNOME ==
+
 
+
KDE and GNOME are popular desktop environments for [[Linux]] and [[UNIX]] platforms. They are storing thumbnails in ''~/.thumbnails''.
+
 
+
Example thumbnail in GNOME:
+
 
+
<pre>
+
$ hachoir-metadata .thumbnails/normal/0d97afdc637ac86d75d13e72172dc77c.png
+
Metadata:
+
- Image width: 128 pixels
+
- Image height: 122 pixels
+
- Bits/pixel: 24
+
- Pixel format: RGB
+
- Compression rate: 1.6x
+
- Compression: deflate
