Relative links

WordPress prefers and pretty much forces absolute URLs whenever it can, as blogs are mainly consumed through syndication. For example, consider this:

Your image is at example.com/image.jpg so you use just the relative URL /image.jpg in your post.

But, I read your blog on http://newsblur.com/ and that image won’t load because it doesn’t exist at newsblur.com/image.jpg

Or, I read your blog via email at https://mail.google.com/ and that image won’t load because it doesn’t exist at mail.google.com/image.jpg

This is why WordPress prefers absolute URLs, so you use http://example.com/image.jpg in your post, and I can see the image in NewsBlur and Gmail because no matter where I’m reading your post, that image is always referencing http://example.com/image.jpg

When you’re ready to move your site, it will be easy to search and replace those links using a plugin like https://ww.wp.xz.cn/plugins/better-search-replace/

You’re welcome!
