# How does uploads work?

 * Does anyone know if a new attachment is only a new wp_post record?
 * I am trying to do an automatic upload engine. But my images isn’t opening like
   the other normal attachments. I can access normal wp attachments by “pagename/
   imagename”. But this structure seems not work for automatic attachments. Every
   new image is being redirects to 404.
 * So I decided to ask it on forum to understand the proccess to create a new attachment.

 * Thank you very much for your help =)
 * **I tested it and that is what happens:**
    When we upload an image through add-
   from-server tab, the new image is attached to the page and the image appears 
   on gallery tab. Looking at the new attachment entry on wp_posts table I noticed
   that post_parent field was setted to the page’s id I am editing. But I still 
   can’t access the image through _pagename/imagename_ permalink.
 * Whether I insert this new image on page I can access the image through _pagename/
   imagename_.
 * **So what I find is:**
    A new wp_post entry isn’t enough to create a new attachment,
   and the page_parent field value isn’t enought to WP find the image through the
   post permalink.
 * So,** what else** happens when an image is attached to a post?
    – upload file
   to server – new post entry where post_type is ‘attachment’ and post_parent is
   page’s id which we are editing – ? (what else?)
 * I still looking for a way to create a permalink to access my images. Any help
   is very appreciated. =)

 * It’s not making any sense for me.. can anyone help?
 * Once a wp_post entry looks like another one (only changing the fields id and 
   post_name), what can take WP find an attachment by name (_domain.com/pagename/
   imagename_), but not the other one?

 * [@michaelh](https://wordpress.org/support/users/michaelh/): Do you know why an
   image listed in gallery tab (when editing a page), but not inserted yet, cannot
   be accessed by a permalink but another image which had already been inserted 
   on this same page can be access by a permalink?
 * I mean, what does WP check before load the image.php? What is the diference on
   database between those two images?
