All you have to do is to set the source from which the program can load wallpapers.The wallpaper images sources like local files and folders, FTP remote folders, Flickr photo stream, Yahoo, Panoramio, Pikeo, Ipernity, and Photobucket images etc available with the program.

• View the info about the current desktop wallpaper on the right
• Select the layout of the wallpaper being set as desktop wallpaper

Advantage of using DocJax document search over regular web search

Inline Preview : It shows the preview of content present in the documents.

It is integrated with Scribd, you can view the entire document without downloading it

Advantages over Google search:

You can search for documents in Google using the filetype operator.But this has few drawbacks

1. Google doesn’t provide “View as HTML” for some documents, then you have to download the entire document to view the what is present inside.

2. If you want to search multiple files then the search syntax gets complex.(example:nanotechnology filetype:doc OR filetype:pdf OR filetype:xls).
