 * Hello,
 * I have problems with some images. It seems that the images are converted to 16
   colors by Nexgen Gallery. When I use a WordPress gallery the pictures are shown
   correct. See my sample page [Testgallery – Managedata Test.](https://test.managedata.de/wordpress/?page_id=27)
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fpixelation%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@managedata](https://wordpress.org/support/users/managedata/)
 * I am sorry to hear about the issues encountered. This is something we are investigating
   at the moment.
 * You can try adding the following to your wp-config.php file and see if that helps:
 * `define('NGG_DISABLE_IMAGICK', FALSE);`
 * You will need to recreate the thumbnails for the failing galleries, if they come
   out fine, please go to **Tools >> Site Health >> Info (at the top)** and then**“
   copy site info to clipboard”**, then paste it on a notepad and please check what
   version of Imagick you have and share that with us. We think this could be related
   to version 3.5+
 * Please keep me posted.

 * Hi Jaime,
   I have added the line to my wp-config.php, recreated the thumbnails
   and deleted the browser cache. No success.
 * I don’t know if this helps but the picture with the correct thumbnail has a format
   of 1800 x 1013 pixels. The file name ends with “-scaled”.
   The other pictures 
   with wrong thumbnails all have a format of 900 x 1200 pixels. The filenames don’t
   end withs “-scaled”
 * The imagick version is 3.7.0:
 * image_editor: WP_Image_Editor_Imagick
   imagick_module_version: 1693imagemagick_version:
   ImageMagick 6.9.13-10 Q16 x86_64 18376 [https://legacy.imagemagick.org](https://legacy.imagemagick.org)
   imagick_version: 3.7.0

 * Hi [@managedata](https://wordpress.org/support/users/managedata/),
 * I just realized the value of the constant I gave you is set to “false”, not sure
   if you noticed, it should have been like this:
 *     ```wp-block-code
       define('NGG_DISABLE_IMAGICK', TRUE);
       ```
   
 * Please try that and let me know again.
 * Sorry for the trouble.
