All the latest posts and images were being indexed on google quite quickly.
Since i've installed Yoast plugin on my site http://www.7tab.in after reading about duplicate content.
I opted for no-follow for tags,categories,archives,sub pages of archives,format,picture tag,author archives and date archives.
Since then, all the latest posts have been getting indexed as usual. However, the images in posts are not getting indexed on google image search. Only the posts which i submit to social bookmarking sites, the images inside these posts are getting indexed on google images.
Rest of the images inside posts which i don't submit are not getting indexed.
Please help me out. Thank you.
