Hello,
I do not know what’s going on, but my highlights images are lousy.
I have tested even in very high resolution, but the quality on the site is terrible!
This happens only on the highlighted image!
example: http://www.tudoemtecnologia.com/review-lg-g4/
I’m trying to make another post with another image and the result is terrible!
Most often this is from using JetPack image tools, which I think suck.
I’m not using jetpack!
This only happens in the highlights of the posts images!
I use a code in my functions.php file to help me sharpen my images..may be it can work for you, but you will have to Regenerate your old Thumbnails images to see the effect but all new uploads after will take effect right away..
function modify_image_before_saving( $image, $post_id ){
if ( ‘attachment’ == get_post_type( $postid ) )
return $image;//add interlace image option
imageinterlace( $image, true );// sharpen image
imageconvolution( $image, array(-1,-1,-1,-1,16,-1,-1,-1,-1) , 8, 0 );return $image;
}
add_filter( ‘image_save_pre’,’modify_image_before_saving’, 15, 2 );
Thank you.
I added the code, but the images are still very bad!
Tested in a post I’m writing, and the highlight image is still bad!
This only happens to FEATURED IMAGE
I’ve used a number of resolutions, but nothing changes, the quality is very low!
What is the ideal resolution of the highlighted image to my site?

@Thalisson i really don’t see the problem of ur images being not sharp,on my HD monitor ur images is sharp and quality looks fine from my end…
They look very good on my high quality Apple Cinema Display (IPS panel, color calibrated), also.
One note: if you’re using the “optimization” setting for the “quality” factor in your functions.php to change from default 90 to the 50 from my optimization sticky post, you can try dialing that back to something like 65.
Also note with ANY image which is predominately “red” — this is the color not well compressed by JPEG; in some cases it’s worth experimenting with PNG/24. In Photoshop any “lots of red” image generally needs at least a “32” level setting and possibly “52” compression setting vs the normal “15-22” you can use for many other images for optimum max compression.
