   Thank you! I transitioned a site over to Divi, then added several galleries. Was blown away buy the file storage glut. This easy solution brought the total storage down to something managable.

   Hi, today I changed all my settings to 0 like shown in your instructions above. I uploaded a new picture and when I attempted to resize in side bar all I have for options is full size (which is too big) and shareaholic from another plugin in my site. I tried setting back to default settings. And it didn’t change still same two options. Any idea how I can fix this?

     If the plugin was already uploaded, you would want to use the regenerate thumbnails plugin for creating a the returned image sizes. We have a guide on how to use it here: https://www.wpbeginner.com/plugins/regenerate-thumbnails-new-image-sizes-wordpress/

   Does not work. You have to modify the functions.php flle. This is one of the most irritating thing WP does. You should be prompted to create multiples sizes after uploading files. It should not be assumed. Bad bad…

   Hello,
   I have a running image sharing website, usually, we insert more than 20 images in a single post. I want to prevent WordPress from generating different image sizes for inserted images, except for the post featured image.

   For example, If there are 20 images in my post. I want WP to generate image sizes for the Featured image only, and for other inserted images i don’t want different sizes.
   Actually, the problem is the limited storage space and the other problem is that with those useless image sizes the backup file has more size.

   How can I achieve this?
   I appreciate your help.

       Hi Lalit and Amit,

       Unfortunately, this is not as straightforward. Your WordPress theme may have defined its own image sizes, some times WordPress plugins may also define new image sizes. First you will need to figure out the sizes you don’t want to use anymore. This may result in unexpected behavior from your theme and or plugin. You will need to know the name used by the theme or plugin to remove the image size.

       add_action('init', 'remove_plugin_image_sizes');
       
       function remove_plugin_image_sizes() {
       	remove_image_size('image-size-name');
       }

       Another alternate could be using a plugin like “Optimize Images Resizing”, which stops generating image sizes upon upload and only creates a new image size when you select that size to insert in the post.

   Great article, but I have a question
   When I hired a developer to do my WP website, he sat the 3 default image sizes to some numbers which always made my gallery images to look pixelated when clicked on and enlarged inspite of using WP retina 2x plugin to make all my images look “retina-quality”, so I sat those sizes to zeroes and tried re-uploading an image and baam, it looks super sharp, however, my subheader images never look as sharp or crisp …. DOES ANYONE KNOW WHY? IT’S DRIVING ME NUTS!!!

   I am using Suffusion theme and beside the three native sizes of 200×200, 300×225, 400×300, I am also getting 96×96, 128×128, 128×72 and 480×360. That’s seven sizes!

   The problem is that all these different sizes may be seen by Google as duplication. That seems to hold water because only a small fraction of my images are being indexed.

   Is there a setting I am missing or plugin that can fix and clean this mess up?

   TIA

     We feel that Google understands that your site may host several smaller or larger versions of an image. It is not duplicate content.

    Very helpful article, I found what generates 88×88 thumbnails in functions.php of my theme! thanks a lot!

    Thanks for the article. More than a year later it’s still useful! I just managed to change my theme to stop creating potentially thousands of variants of images I intend to have in WordPress galleries. However, what I did was
    (1) to comment out the add_image_size( ‘square100’, 100, 100, true ) as suggested, and
    (2) to replace the parameters to the_post_thumbnail call (see WP Codex) with an array e g
    the_post_thumbnail(‘square100’) became the_post_thumbnail( array(100,100)).
    This stopped the unnecessary creation of variants for every image loaded.
    To do this I had to override various functions and files in the theme by using a child theme, which is a whole subject on its own, and not to be attempted if you don’t have good knowledge of how child themes work!

    Hi do you happen to know how to unregister
    add_image_size
    set_post_thumbnail_size?

    While removing the line works i wouldn’t like to modify the theme and unregister on my child theme, so i don’t have to remember to do it again every time the theme updates.

    Thank you.

    I just read this and my theme and wordpress combined is generating 25 copies of each photo! I use a lot of photos on my site, the big question is how do we know which ones we can erase, i think three sizes is more then enough, but 25 sizes!

    Any thoughts WPBeginner!

    Hi there, I think you’ve overlooked a way to decrease the number of generated image sizes;
    First, as you mention, get an overview of image settings in WP, theme and perhaps plugins – jot them down, px by px.
    Secondly, decide what is needed according to your visual needs. Often there’s small differences in e.g. thumbnail size but you can do with just one global size.
    Then lastly, align as much as possible, i.e. keep all the image settings but try to set as few variations as possible.
    I’n not in favor of messing around with the code since too often something will break down the road but this is just good practice of knowing what you want

      Jens, would you mind private messaging me? I’m having a heck of time trying to reduce the amount of images on my site. My host is going to shut it down.

    Is there a computer–mac- windows-or chrome book, etc that lends itself to easier/better writing a wp blog—.com, not org? any overall ease of use for a newbie, like me?

    There is a plugin called “Regenarete Thumbnails” (and another one “Force Regenerate Thumbnails”) which will resize existing images according to the new configuration. At least the second one promises to also delete the old resized images.

    I want to keep the thumbnails and rest I want to ignore, so, I will change only other 2 options than Thumbnail and If this will work…

    Thanks for the interesting article !

    You mention the “uploads” folder but there is also the: /wp-content/uploads/et_temp folder which in my case is also full of copies of images. Can you shed some light on the purpose of this particular folder. I am using a “Elegant Theme” called Envisioned.

    Thanks & Cheers,

      Seems like your theme or may be a plugin is responsible for adding images into this folder. Unfortunately, we can not specifically provide help with individual theme and plugin settings. You will need to contact your theme or plugin support and ask them how you can prevent this.

    Thanks for another useful article. I’m just wondering whether removing the various image sizes would have an adverse effect on mobile/responsive WP sites. Don’t we need those sizes so the images can adjust to various screen sizes and orientations?

      Not always true. Many themes use jQuery and css to make your images responsive.
