Blurry images in WordPress

  • Hi c-m,

    Inside the settings page you can define media sizes on upload, maybe this will help you.

    That’s what this code does:

    add_image_size( 'medium-thumb', 867, 578, false);

    I then select ‘medium-thumb’ as my image size when adding the image to the post.

    Hello C-m,

    I tried to see I could duplicate the problem that you’re having but I’m unable to see any fuzzy thumbnails with the images you provided. I also checked my functions code and I see nothing similar. I am running the latest version of WordPress 4.5.3.

    Are you running the same version? Using any plugins? I also checked my Settings under Media and these are the dimensions that I have set:

    thumbnail – 150×150
    medium – 300×300
    large – 1024×1024

    Do you see the same type of thing? Please let me know and we can follow up if necessary.

    Regards,
    Arnel C.

    Yes I see the same thing, except I see the sized I set i.e medium is 867 width with no entry for height.

    I added the code in the post above because I want an image called medium-thumb with those dimensions. I call it in my theme at certain points.

    In the actual media settings I don’t set a height, otherwise it’ll screw up any images taken in portrait.

    Quality is set to 100, and sharpening is turned on for re-sampled images.

    Still a big quality loss. It has to be something that PHPthumb is doing when it creates the various image sizes.

    Here’s another comparison.

    This is medium sized thumbnail resized by wordpress with quality at 100%

    This is one outputted from lightroom at 867×578

    If you open them in a different tabs and switch back and forth the differences become very apparent. Looks at the front tyre, the number on the front, and the grass.

    It’s not make or break on this image due to it’s subject and composition, but on others it is.

    I sorted it by just using a using a plugin that accesses some sharpening function in ImageMagiks library.
