To hide an MP3 file into a JPEG image, copy the MP3 file and a picture into a folder. Open the command prompt window (Start –> Run –> cmd) and switch to this folder. Now run the following command: copy /b my_picture.jpg + my_song.mp3 my_new_picture.jpg Remember to replace my_picture and my_song with relevant file names. Next, upload the my_new_picture.jpg file to Flickr. The MP3 song picture will look just like any other regular photograph that you share on Flickr
