Echo Images inside a Post into the Loop
Here is a useful trick. Want to call or echo an image into your blog post with our using the custom fields? Well this could be tricky, but I know of a way.
All you have to do is print these lines of code into your
index.php or home.php inside the loop:
<?php
$id =$post->ID;
$the_content =$wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $id");
$home = get_option('home');
$pattern = '!<img.*?src="'.$home.'(.*?)"!';
preg_match_all($pattern, $the_content, $matches);
$image_src = $matches['1'][0]; ?>
then after write:
<?php if($image_src != '') { ?>
<a href="<?php echo the_permalink() ?>" rel="bookmark" title="Link to <?php the_title(); ?>"><?php the_title(); ?></a><br />
<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php echo $image_src; ?>" alt="<?php the_title(); ?>" /></a>
<?php } ?>
That’s all! This will look for the first image in your post and echo it in the loop, could be used to show off those pretty thumbnails for the post..

HTTP stands for Hypertext Transfer Protocol, and it’s the foundation of the web we know today. It’s a set of rules that govern how web servers and browsers communicate with each other to send and receive information.
To understand how HTTP works, let’s consider a simple example. Imagine you want to visit a website, so you type its URL into your browser and hit enter. Your browser sends an HTTP request to the server hosting the website, asking it to send the webpage back to you.
The server receives the request and responds by sending an HTTP response back to your browser. This response includes the HTML, CSS, and JavaScript that make up the webpage, as well as other resources like images and videos. Your browser then uses this information to render the webpage on your screen.
HTTP is a stateless protocol, which means that the server doesn’t store any information about the client’s session. Each request is treated as a separate, standalone event. This is in contrast to protocols like FTP (File Transfer Protocol) or SMTP (Simple Mail Transfer Protocol), which maintain a connection between the client and server for the duration of the session.
One of the key features of HTTP is that it’s based on a request-response model. The client (usually a browser) makes a request, and the server responds with a response. There are several types of HTTP requests that a client can make, including GET, POST, PUT, and DELETE.
GET requests are used to retrieve information from the server. For example, when you visit a webpage, your browser sends a GET request to the server to retrieve the HTML, CSS, and JavaScript that make up the webpage.
POST requests are used to send data to the server, usually as part of a form submission. For example, when you fill out a form on a website and click “submit,” your browser sends a POST request to the server with the form data.
PUT requests are used to update a resource on the server. For example, you might use a PUT request to update the information in a database record.
DELETE requests are used to delete a resource on the server.
HTTP is a crucial part of the internet, and it’s what enables us to access and share information online. Without it, the web as we know it wouldn’t exist.
In addition to the request types mentioned above, there are also several HTTP response codes that a server can send back to the client. These codes indicate the status of the request and whether or not it was successful.
Some common HTTP response codes include:
- 200 OK: The request was successful and the server was able to fulfill it.
- 301 Moved Permanently: The requested resource has been moved to a new URL, and the server sends this response code along with the new URL.
- 404 Not Found: The requested resource could not be found on the server.
- 500 Internal Server Error: An error occurred on the server while processing the request.
HTTP is an important part of how the web works, and it’s something that most of us use every day without even thinking about it. Whether we’re visiting a website, filling out a form, or uploading a file, we rely on HTTP to send and receive information.
It’s worth noting that HTTP is just one of many protocols that make up the internet. Others include TCP/IP (Transmission Control Protocol/Internet Protocol), which is the underlying protocol that enables the communication between computers on the internet, and SSL/TLS (Secure Sockets Layer/Transport Layer Security), which is used to encrypt communication between a client and server.
Find an overview of HTTP Protocol here. and additional information on HTTP protocol here.
In conclusion, HTTP is a vital part of the internet, and it’s what enables us to access and share information online. Whether we’re browsing the web, filling out a form, or uploading a file, we rely on HTTP to communicate with servers and other clients.

Assuming the image has been added using the WP uploader, here’s a way of doing the same thing using the WP API, which might have a performance advantage:
<?php $attachments = (array) get_children(array(‘post_parent’ => get_the_ID(), ‘post_type’ => ‘attachment’));
if ( ! empty( $attachments ) ) :
$attmt = array_shift($attachments);
$image_thumb = wp_get_attachment_thumb_url($attmt->ID); ?>
<a href=”<?php echo the_permalink() ?>” rel=”bookmark” title=”Link to <?php the_title(); ?>”><?php the_title(); ?></a><br />
<a href=”<?php the_permalink() ?>” rel=”bookmark” title=”<?php the_title(); ?>”><img src=”<?php echo $image_thumb; ?>” alt=”<?php the_title(); ?>” /></a>
<?php endif; ?>

Hi all,
First of all, very nice script. I noticed that the output was in html (ie, img src and thumbnailing).
Does anyone know of any snippet to be able to echo the image via php, without having to name the actual individual image file (eg. tree.jpg), and instead using a variable from a database that names photos in a directory.?
thanks
