this is my post…take a look in my featured image, and then click on her and take a look when she opened in lightbox. picture in lightbox is perfect quality and why featured image doesn’t have that quality? can i fix that? any suggestion ? please

I believe it’s because of the responsiveness.

Hi,
when image is in lightbox it’s look ok, like on your screenshot… but featured images without lightbox wasn’t ok, please watch this post: http://crnjaci.com/fotovideo-bez-iznenadenja-u-posljednjoj-veceri-drugog-kola-bozicnog-turnira/ did you see different between image without lightbox and with lightbox? for me, without lightbox is several time worse, it is not clean and clear

thank you for your support

Hi!
Regenerate Thumbnails and WP Smush.it, it is look like everywhere image is worse then images in lightboox 🙁

Hi Lucian
If i do that, how big will be images on the server? my default images is about 0.5 MB – 1 MB. Will images be upload on server in that size or size like as determined by smush it?

Look i have this same issue and after putting this lil info at the bottom of my function file it solve my issue…what this code does is sharpen all ur images… you can try it and see if it work for you…

function ajx_sharpen_resized_files( $resized_file ) {

$image = wp_load_image( $resized_file );
if ( !is_resource( $image ) )
return new WP_Error( ‘error_loading_image’, $image, $file );

$size = @getimagesize( $resized_file );
if ( !$size )
return new WP_Error(‘invalid_image’, __(‘Could not read image size’), $file);
list($orig_w, $orig_h, $orig_type) = $size;

switch ( $orig_type ) {
case IMAGETYPE_JPEG:
$matrix = array(
array(-1, -1, -1),
array(-1, 16, -1),
array(-1, -1, -1),
);

$divisor = array_sum(array_map(‘array_sum’, $matrix));
$offset = 0;
imageconvolution($image, $matrix, $divisor, $offset);
imagejpeg($image, $resized_file,apply_filters( ‘jpeg_quality’, 90, ‘edit_image’ ));
break;
case IMAGETYPE_PNG:
return $resized_file;
case IMAGETYPE_GIF:
return $resized_file;
}

return $resized_file;
}

add_filter(‘image_make_intermediate_size’, ‘ajx_sharpen_resized_files’,900);

Oh if you choose to use that code you will need to Regenerate Thumbnails after to see any effect…
