So starting mplayer with these parameters you will have a window with no frames, borders whatsoever, and selecting the window a hitting the "F" key you will bring it in fullscreen. if you want to position the frame somewhere else, you could play with the --geomeptry option where 100%:100% mean bottom right corner.

To keep your inbox clean, it is still possible to filter and move to trash video surveillance emails (and restore these emails only if you really get robbed!) For instance with Gmail, emails sent to [email protected] can be filtered with "Matches: DeliveredTo:[email protected]" Show Sample Output

search the newest *.jpg in the directory an make a copy to newest.jpg. Just change the extension to search other files. This is usefull eg. if your webcam saves all pictures in a folder and you like the put the last one on your homepage. This works even in a directory with 10000 pictures.
