Have you ever set a desktop wallpaper from Safari, only to wish you had saved the file directly so you could access it later or do something else with it? As long as the desktop picture is still set, you can retrieve the original wallpaper image file easily:
- From the Mac OS X Finder, hit Command+Shift+G and type ~/Library/Safari/ as the path
- In the Safari folder, look for “Safari Desktop Picture.*” the suffix could be .png, .jpg, or whatever other image type the original picture was
- Copy the “Safari Desktop Picture.jpg” file to the desktop
The copied file is the wallpaper, you could also move the file instead but moving it will cause the desktop picture to change on next reboot because the source file is no longer in place.
Any background image set through Safari will always show up in that directory.
