  Chris M Cloutier: Hey guys!
  I gotta question about sitemaps.  ;Specifically ;All in one SEO's sitemap.
  
  I have a plugin that seems to make a page for every image I upload, whether I want it to or not.  ;Should I be removing these from my sitemap?
  
  Also, does anyone know of any good resources to read up on and learn about sitemaps?
  
  Thanks guys, you rock!

  Jeff Guest: Hi Chris
  Which plugin are you using?
• 
  Chris M Cloutier: I'm kinda embarrassed to say it, but I'm using the builder plugin from elegant.

  I'm only using it on 1 page, but the page is a portfolio, so it has lots of images.

  Tony McCreath: Those pages are normal I believe. I think Yoasts SEO plugin has an option to disable them. It should also exclude them from the sitemap.
• 
  Jeff Guest: Yes it does Tony, and lots more too!
• 
  Chris M Cloutier: All in one will let me exclude all images from the sitemap.  ;Should I do that?
• 
  Tony McCreath: +Chris M Cloutier I'd try it and see. Sounds like the right thing.
• 
  Chris M Cloutier: Thanks guys I appreciate the help.

  Shubhashish Shukla: You must try YOAST SEO plugin. ;

  Chris M Cloutier: +Shubhashish Shukla ;I've been thinking about switching, but I've been using All in one for years.  ;Maybe someday I'll take the leap.
