How Do I Get an Image From a Folder in WordPress?

You can access images from folders in your WordPress website by using the wp_get_attachment_image_src() function. This function allows you to retrieve the image URL, width, and height based on the attachment ID.

Here's a step-by-step guide:

1. Find the Attachment ID:

• Upload your image to the Media Library: This will automatically create an attachment post for the image.
• Locate the image in the Media Library: Click on the image to open its details.
• Find the Attachment ID: This is a numerical value displayed in the image details.

2. Use the wp_get_attachment_image_src() function:

• In your theme file or a custom plugin: Add the following code, replacing [ATTACHMENT_ID] with the actual attachment ID:

$image_src = wp_get_attachment_image_src( [ATTACHMENT_ID], 'full' );
$image_url = $image_src[0];

• Explanation:
  • wp_get_attachment_image_src() fetches the image URL, width, and height.
  • [ATTACHMENT_ID] is the attachment ID of your image.
  • 'full' specifies the image size (you can use other sizes like 'thumbnail' or 'medium').
  • $image_url stores the image URL retrieved from the array.

3. Display the image:

• Use the $image_url variable to display the image:

<img src="<?php echo $image_url; ?>" alt="Image description">

Example:

Let's say the attachment ID of your image is 123. The code would look like this:

$image_src = wp_get_attachment_image_src( 123, 'full' );
$image_url = $image_src[0];

And you would display it using:

<img src="<?php echo $image_url; ?>" alt="My Image">

Additional Tips:

• Use the wp_get_attachment_image() function: This function directly outputs the image HTML code, making it even easier to display images.
• Use image sizes: WordPress allows you to define different image sizes for better optimization. Refer to the WordPress Codex for more information on image sizes.

By following these steps, you can easily access and display images from folders in your WordPress website.
