 The following is an example of a problem that happens to me regularly
 across multiple sites.

 I have an image size registered as follows:

 {{{#!php
 add_image_size( 'featured-home', 1600, 600, true ); // width, height, crop
 }}}


 When I run wp_get_attachment_image_src() as follows:

 {{{#!php
 $image = wp_get_attachment_image_src( $post_id, 'featured-home' );
 }}}

 ...and then print_r() the result, I get this:

 {{{#!php
 Array
 (
     [0] => http://localhost:8080/lacoastalservices/wp-
 content/uploads/2016/09/wetlands-1600x600.jpg
     [1] => 1080
     [2] => 405
     [3] => 1
 )
 }}}

 The image itself is actually 1600 by 600 pixels wide, but for some reason
 the width and height values given in the array are "scaled down" to the
 width of the next largest image size on the site (1080px), and the
 corresponding image height if it were actually that wide (405px).

 Note that WordPress's "large" default image size is still at its default
 of 1024px, so I don't think that's the problem.

 You can hopefully reproduce this by running the "Display All Image Sizes"
 plugin on a few sites and looking for images whose larger image sizes have
 a mismatch between their identified dimensions and their actual urls.
 "Display All Image Sizes" is using wp_get_attachment_image_src() to
 generate the text strings that describe image sizes, which is how I became
 aware of this bug.
