  • Did you upload images after adding these lines or before it? Nov 17, 2013 at 14:34
  • Im edit function.php and after that im try upload images Nov 17, 2013 at 14:50
  • To apply changed thumbnail sizes to already uploaded images you have to regenerate the thumbnails, for example with the plugin Regenerate Thumbnails Nov 17, 2013 at 15:04

I believe you need to pass the third $crop parameter to set_post_thumbnail_size. In other words...

set_post_thumbnail_size(80, 80, true); 

That third parameter enables a "hard-crop" mode. From the Codex:

Set the default Post Thumbnail size by cropping the image (either from the sides, or from the top and bottom):

Without that argument, or with it set to false, you get a resize without distortion-- ie. as close as possible to your dimensions. Also from the Codex:

Set the default Post Thumbnail size by resizing the image proportionally (that is, without distorting it):

You too, can add a Thumbnail size using add_image_size().

<?php add_image_size( 'email', 300, 200, true ); ?>

Then you can user from your theme:

<?php
if(has_post_thumbnail()) {
    the_post_thumbnail('email');
}
?>
