Hi Steve,

Have you seen by any chance the latest version 2.8.4 – do we still have the same image quality or is it improved?
I’m getting quite low-quality thumbnails with the default settings so I’m wondering what should I tweak in order to improve the quality.

Thanks
George

The thumbnail creation code has been changed considerably and has been moved since I first published this entry. Looking at version 2.7, the code now resides in wp-admin/includes/image.php. Look for the line (at or around line 71):

if ( imagejpeg( $dst, $dst_file ) )

As before, it just needs the third argument that specifies the image quality. I haven’t tested it, but that should work.

Thanks, you exactly answered the question I was googling! I use the multifile-upload plugin which allows you to upload multiple files at once and specify the thumbnail size for each, but the image quality of the thumbnails is still pretty garbage. It uses wp_create_thumbnail() so I might try your hack, otherwise it’s back to Adobe…

Thanks for this, it really came in handy. I’m making “thumbnails” 418 pixels wide, so any quality improvement helps.

I find though that if the source image is pretty big, the result isn’t near as muddy as your example here, which is just as well, as I’m doing this all to avoid having to generate my own feature images.

Cheers and thanks again.
