How to add post image to blog

You should check out Mark Jaquith’s post: https://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/

You can set a featured image when creating a post, then use the code in Mark’s post to display the image on the different parts of the site.

If your theme has a category.php template, you’ll want to edit that for the small image, and edit single.php to display the full size image.

Great response.Thank you
