The main thing is that the "promoting her latest single" type of image is used on multiple pages. For instance, all use the same image at the top. So with LSI instead of having to update each page that uses the image, you can just edit the line in Template:LSI where it has  |Oda Sakura = OdaSakura-AreyouHappy.jpg  and all pages will be affected.
 * List:Oda Sakura Discography Featured In
 * List:Oda Sakura Pocket Morning Weekly Q&A
 * Gallery:Oda Sakura

Since these usually come for an entire group together, this also means that after uploading, say, Morning Musume pictures, you just need to update the Morning Musume section of LSI rather than messing with 30+ pages separately.
