I haven't explored the picture option, so hopefully someone else can tell you.

Move your music from where? You can set up (create) a folder & move your music to it (drag & drop, or go to yor Windows menu bar & select the command that best suits; eg: Put your mouse cursor onto the music file to highlight it, Cut, Copy to Folder, or Move to Folder. And paste if you choose either of the 1st 2 depending on whether you want to keep a copy where it was or move the original to a shared folder.)
After having setup a folder with the music in it, go to Limewire's menu bar at the top & select Tools-Options-Sharing & press the Add button. Now you can direct LW to where your new shared folder is. Then press Apply & OK. Now go to LW's Library window & press Refresh. You will now see your new shared folder in the list. Press onto the folder's name & you'll see it's contents with the music inside it. Hope I explained it clearly enough b/c I'm on a Mac, not a PC. Answer back to this thread if you're still having problems.
