Custom image sizes for custom field media uploads

2 Views

Is it possible to resize my image uploads to different settings, depending on what custom field I’m on?

I’m using wpalchemy, and have an image uploader for a heap of different custom fields. It would be great if I could detect which custom field I’m currently on, and have different dimension options.

For example, if the custom field is my_special_image, I could stipulate 960x200px hard cropping, similar to featured posts.

  1. Have you considered using WP’s add_image_size function? Here’s the Codex entry.

    Basically you could add all the sizes you require throughout your theme via your functions.php and then call the appropriate size in your page/post template.

    Good luck!

  2. Add this to your themes functions.php file underneath your existing image sizes:

    add_image_size( $name, $width, $height, $crop );

    Example:

    add_image_size( 'home-bottom', 280, 150, TRUE );
