Why my Categories’s content not URL

Use absolute links (src=”https://site/path-to-image/image”) and not a relative link (src=”image”)

Another option is to set links to start at the root or top of your path, using a forward slash at the beginning (src=”/images”), or wherever your image directory happens to reside, starting from the root (src=”/blog/images”).

thanks , but not absolute path wrong,such as this links,it can display from first page, but can’t display from Categories’s . I think is a wrong of php function, maybe the function filter this.
<img src=”https://photos.gznet.com/photos/1077891/1077891-mn9LmKFN6O.JPG&#8221; alt=”” />

Then your category page is probably set to show the_excerpt which will not show the image.

yes ,I find it the_excerpt() function for this post ,
what function I can use ?instead of the_excerpt()??
thanks

thanks, I use the function of <?php the_content(‘Read the rest of this entry »’); ?> instead of the_excerpt()
in the index.php ,the problem has resolved.
