Where is the assets library?

Ever wondered about why site Assets is on some sites but not all? I’ve heard speculation that it’s hidden. Well nope it’s just not there. It’s created through the activation of the Wiki home page feature. Go figure huh.

What’s even stranger is that if you open a site that doesn’t have a site assets in SharePoint Designer it will still have the Site Assets library listed there. You click on it, it’ll think about it for a bit and go ahead and create the library for you on the site.
