Use image url with add_image_size

2 comments

1. The pattern you posted…

   www.mydomain.com/image.jpg('custom-thumb');
   

   … is a bit odd. That would be pretty tricky. You’d need a PHP handler to load the image and you’d need to tell the server (Apache, Nginx, IIS, Whatever) to parse that file ending as PHP. Something like this would be simpler:

   www.mydomain.com/image.php?size=custom-thumb
   

   You would still need to create a PHP handler script to read the URL, parse the GET string, and display the image.

   You could probably get something like this…

   www.mydomain.com/image/custom-thumb-X
   

   … working with an endpoint.

   However, the easiest thing to do is use wp_get_attachment_image_src to create the URL. I don’t know if that is an option for you but there is an example in the Codex:

   <?php 
   $attachment_id = 8; // attachment ID
   
   $image_attributes = wp_get_attachment_image_src( $attachment_id ); // returns an array
   ?> 
   
   <img src="<?php echo $image_attributes[0]; ?>" width="<?php echo $image_attributes[1]; ?>" height="<?php echo $image_attributes[2]; ?>">
   

2. TimThumb (source code) is probably what you think you need, and probably good enough now, considering that it’s been a while since it was last exploited. Like anything else, it comes with its own pros/cons (just google ’em).

   But you should know that once you get the hang of add_image_size and the_post_thumbnail functions you’ll never have to go back.

   PS: Besides it looks like an XY problem. So, considering that you think X is the solution to problem Y, why don’t you tell us more about Y, and see if we can suggest a better alternative to X?
