Whilst surfing the web, I found not another sprite page, but a forum containing MANY sprite page links! Individual sprite pages are useful, but this is a solid block of links leading to different sprite, background, etc pages! The guy who posted this forum is quite helpful to us who are too lazy to look for pages ourselves.
There are many sprite sites out there, and many of them have sprites others don't. So, to save you the trouble of googling multiple sites for a specific sprite, I'm posting a THIRD sprite site. I know of a couple more, too. This one is great because they copied the sprites from their favorite videogames. There are many users, all posting sprites!
This site is quite similar to the one that I posted before. One huge difference is, although it does have less sprites, it also has sounds, backgrounds and many other things like that. One special thing also on this site is custom sprites. My previously posted site only has videogame sprites. This site has some sprites people custom made from their favorite show, comic, etc. It could be very useful to you!
This website is what I use for ANY sprite from a video game. I've been using it for a number years, it is very user-friendly and easy to use. Click the search bar and type in a video game. Any sprites at all relevant should show up. It is VERY useful for finding what you need. There are over 1000 spirte sheets, which is a LOT of sprites.
