Site Maps for Images and SEO Search Engine Optimization

After a lot of research, I discovered just how important site maps are for allowing search engines like Google to include my images in their search results. With so many websites in the world it makes sense to have some type of guiding file that tells the search engine robots whats really important on your site so it can quickly get in an out and on to the next site.
I also learned you can have multiple site maps on your website and there is this little robot text message file that can tell the search engine robots what sitemap files to use and what directories to ignore.
Looking forward to the coming weeks so I can see what a difference it makes in overall presence I have on the web.
