If you found your blog is not working with Zemanta image and referencing system, you are probably not alone. It was a true handy way to blog, however it’s removed. While searching the cause I found the following information in a WordPress forum (thought sharing it will be of worth):
On January 2nd, 2014 we’re removing our third-party integration with Zemanta, which added some tools like a manual related content tool, and suggestions for tags and images.
Our goal is to provide the best, most transparent, editing experience and, for a variety of reasons, felt that it was needed to develop our own tools internally. To that end, we’re working on improving our editor to incorporate some of this functionality natively within WordPress.com. Some features, like related posts, are already there.
In the meantime, we encourage you to use our own Related Posts feature, and for images, check out our list of websites that provide free images, videos, books, and other content for your blogs.
In the mean time I found few interesting links that you might find helpful in this regard:
- https://support.google.com/websearch/answer/29508?hl=en (handy one I think)
I particularly find the deficiency of auto tag suggestions, quite mourning. Hope, WordPress team will not depress their users and definitely bring something interesting and enjoyable as alternative.
