# Keep perspective using post thumbnails

 * Is there a way to keep the perspective when using post thumbnails.
 * I currently have this in my functions.php
 *     ```
       add_theme_support( 'post-thumbnails' );if ( function_exists( 'add_image_size' ) ) add_theme_support( 'post-thumbnails' );
       if ( function_exists( 'add_image_size' ) ) {
       	add_image_size( 'cat-thumb', 50, 50 );
       	add_image_size( 'single-post', 317, 150);
       }
       ```
   
 * Instead of giving a height in pixels, I’d like to allow it to keep the perspective.
   Is there a way of doing this?
 * As you can see, the first page below looks ok, but the second is terrible:

 * I assume that you want your width not to change, but for the height to be proportional
   to the width?
 * If you find that images are being distorted, try setting your `$height` argument
   to something very large, e.g.:
 *     ```
       add_image_size( 'single-post', 317, 999);
       ```
   
 * Since you’ve left `$crop` as `false`, this will ensure that images box-resize,
   rather than crop. One of the two dimensions needs to be given freedom to resize,
   if you’re doing a box-resize, rather than a crop.
 * The other thing is to ensure that the _original size_ of your image exceeds your`
   add_image_size()` dimensions. WordPress does not zoom-crop.

 * It’s a bit strange. When I change the sizes in functions.php, it makes no difference,
   it still uses that original size for some reason.
 * If I use this in single.php, it makes the height 999 pixels
 * `<?php if ( has_post_thumbnail()) the_post_thumbnail( 317, 999 ); ?>`

 * Did you regenerate your Thumbnails after changing the arguments in `add_image_size()`?

 * Thanks, that sorted out the problem.
 * I found this plugin, which made it as simple as anything:

 * Great! So your Thumbnails are all retaining their proportion now?
