image height not showing properly

The theme resizes them with PHP.
Search for this line:

add_image_size( 'twentyfourteen-full-width', 1038, 576, true );

in this page:
https://themes.svn.www.ads-software.com/twentyfourteen/1.0/functions.php

to see.

Any suggestions on what can I do?

First create a Child Theme:

Hi Andrew,
I will try doing those changes. Thanks for the tip on creating a child theme.

When I have issues with adding new image sizes, I find that it doesn’t work on images that have already been uploaded. You have to reupload the image for it to recognize it due to WordPress cropping and saving a copy of the image when it uploads and not during the process of calling it to the page.

Hi Andrew,
I found the line:
add_image_size( ‘twentyfourteen-full-width’, 1038, 576, true );
Any guess on what would the right value in order for the images to show properly?
I already tried diferent values and I saw no change.
Thanks!

Thanks Apput, let me check if that might be the issue.

You where right Apput, images need to be uploaded again.
Also, I see that for that line
<?php add_image_size( $name, $width, $height, $crop ); ?>

If I false for $crop, it would not crop any of my images?

Note that you should be making your changes within your Child Theme. If you want to know how, just create a functions.php file in your Child Theme folder and within that file redeclare the add_image_size function with your modifcations:

<?php

add_image_size( 'twentyfourteen-full-width', 1038, 576, true );

?>

The $crop parameter is referring to whether or not you want to hard-crop it. Hard-crop is when you don’t care about the image proportions and crop it anyway. False here would mean you want to soft-crop it.

What happens if you just pass the $name in and forget about other parameters?
