[MPlayer-users] MPlayer - playing JPG

[David Hepburn]

mplayer plays my videos like a legend.
However, I would like to know how to play a JPEG image for say 15 seconds using mplayer line command. I've tried various options but I seem to always get the msg "[image2 @ 015799e0]Could find no file with path 'mp:C:\Program Files (x86)\MediaUnleashed\test.jpg' and index in the range 0-4
LAVF_header: av_open_input_stream() failed"

The line command issued is:-
mplayer.exe "C:\Program Files (x86)\MediaUnleashed\test.jpg"

I've also tried adding various options like "-vo jpeg"

Could somebody please send me the line command required to run on Windows.
Thanks.
Dave.
