Hey, check out this site I found. It's not in english, but it has images for almost all of the Super Sentai series.
Here are some images I found. (There where some images with two pages seperated on their site, but I used "Paint" to put them back together.) Enjoy! And go visit this guy's site.
Bioman Robot Fighting
Dyna Pink, with a little battle damage
The faceless Samurai warrior, Heavenly Ninja Shurikenger
Fanged Ninja Kuwaga Raiger
