image quality suddenly degraded

site?

whistlinggirlknits.com

can you recollect any changes made to core or new plugins/etc added from 3rd till now?

the problem wit JPG is that they loose quality with every save. also, i think WP uses GD tool when images are uploaded. so am sorry to disappoint you but in my opinion, you cannot regain the lost quality of existing pics.

for future uploads,
try adding this to functions.php:

add_filter('jpeg_quality', function($arg){return 100;});
add_filter( 'wp_editor_set_quality', function($arg){return 100;} );

we change quality from 90 to 100. but again, remember that thats compression happening at 100% image quality. there is still a loss.

and be careful with plugins. are you using any image optimizer/gallery/etc plugins? can you disable them and check. remember to flush cache.

ofcourse, everytime you check, you check with a new image upload.. not with existing.

I didn’t touch the site at all, which is what’s so frustrating. I feel like there must have been some upgrade forced through on the back end that’s causing the problem. When you say the jpegs lose quality with every save, what does that actually mean? I am working with a raw image in Lightroom, saving as a jpeg, and then importing that jpeg into my media library to add to my post. That’s one save, right? Or do you mean that every time I edit the post and update it the picture quality is degrading? I’ve been into my latest post A LOT trying to solve the problem, but I’ve also been deleting the affected images from my library and uploading fresh ones, so to me it seems like this still shouldn’t be an issue. I’ve also turned off the image script, but to no avail. And nothing explains why older images in posts that haven’t been edited and in my sidebar and footer are suddenly degraded.

The only plugin I’m using for the images is Lightbox, and they look just fine there. I’ve deleted the cache. I’ve rebuilt thumbnails. But all older images that are displayed at less than full size are still degraded, and my full-size new images are just as bad.

sorry for the delay..
well if you havent updated the site with any new plugins/themes/file-changes/etc, and your upload procedure hasnt changed, then its gotto be the server. it cant be magic! ??

so first up, check with your hosting people if they have made any changes to server, including upgrades, esp for php.

also if you have a development/staging server/pc, then you enable logging all over, if production server then disable display errors option.
set WP_DEBUG true in wp-config.php.
check all your core dumps.
turn on log_errors PHP option and check:

@init_set ( 'log_errors', 'on' );
@init_set ( 'display_errors', 'off' );
@init_set ( 'error_log', '/<some-path>/php_error.log' );

create that file php_error.log first and give the right path.

also, WP3.8.2 has updated ‘Plupload’. i dont know if thats doing some footprint compression by lessening quality. maybe the pros can put in a word if they read this..

Shadez, just wanted to thank you for your help… figured out it was a page speed issue controlled by my host. Of everyone I talked to in trying to chase this down, you were the most helpful!

All best,
Sarah
