Did you save all of your images as "Save For Web"? You can do this with most graphic programs. If you have Adobe Photoshop Elements, look under "File". Or, if you use Microsoft Office, use the Picture Manager and it also has this function.

Music: Using Windows Media Player and the Audio Coverter function, you can convert files to MP3 and choose the quality. Select a lower quality and this will reduce the size greatly...and it is difficult to tell the difference in quality.
