Webilder is a free and open-source software released under the BSD license that delivers stunning wallpapers to your Linux desktop, directly from Flickr and Webshots.

You choose what keywords (tags) to watch for, and photos are automatically downloaded to your computer. Webilder can also change the wallpaper every few minutes.

Installing Webilder

Download Webilder from http://www.webilder.org/static/downloads/Webilder-0.7.1.tar.gz and unpack it into any directory, for example on your Desktop. After you have the files, open a terminal and install the needed dependencies:

sudo apt-get install python-gtk2 python-glade2 python-imaging python-setuptools

sudo apt-get install python-gnome2 libglib2.0-0 python-appindicator gettext

Next, still in terminal, change into the directory where you have unpacked the files to and install them. They are in the webilder-0.7.1 folder, so in my case I enter:

cd /home/username/Desktop/webilder-0.7.1

sudo python setup.py install --install-data=/usr

Be sure to replace in the installation path the username with your actual username.

Starting Webilder

If not started automatically, rightclick your desktop panel and select Add to Panel....

Browse the available applets and click on the Webilder Desktop Applet. Click on Add and the applet should appear on your desktop panel.

If the applet is not available in the list of applets, just restart your system and it should appear in the list.

Webilder Preferences

Leftclicking on the camera icon on the panel will give you the important menu options to deal with Webilder, like Preferences.

Here you can specify the intervals of rotation and download of wallpapers, which wallpapers should be downloaded and where they should be downloaded from.

To add filters, head to the flickr tab, use the Add button and click on the filter fields to configure it.

To browse the wallpapers already downloaded, leftclick the icon on the desktop panel again and choose Browse Photos. They are organized in recently downloaded photos and monthly categories, however you can also add your own albums.

You can also delete, download and switch wallpapers manually by leftclicking the panel icon and selecting the appropriate action.
