How to Remove authomatically created Image posts

Yes, WP automatically creates a page for every image added to the Library.
This page only shows if a visitor clicks on the image like I did on your image https://techseotricks.com/wp-content/uploads/2014/03/google-webmaster-giving-keywords-1.png.
You can deactivate this function when you insert an image to your post or page an set the link to NONE in the lower right part of the screen under attachment display settings.

Hi marie, Thanks for your reply.
Well, a seperate page for each of the image is created in wordpress and that’s okay.

I am talking about this link

If you see the aobe page then you will find that there is a new post created in the name of the image and the image name is added at the end of the post URL.

There are around 350 images on my blog so 350 posts are created automatically.

See my attachment sitemap
https://techseotricks.com/attachment-sitemap.xml

an individual URL is created for each of the image.

Hi Bhavuk,
Strange it never happened to me. I’m no developer of WP sites, just a user. But I looked at your linked page source and all I can see in it are scripts. Not the standard wordpress produced code. And at the end this line
Served from: techseotricks.com @ 2016-02-11 02:56:22 by W3 Total Cache -->

So I guess problem stems from a plugin/script or some settings in w3 TC.
Sorry I can’t be of any help on this matter.
