    Disable Automatic Generation of Thumbnails, by dago91


    I’m quite new to WordPress and I’m just working a bit on the website of somebody else, so I didn’t create it myself.
    My problem is the following: I want to upload PDF files and everytime it automatically creates 4 JPG’s of different sizes with previews of the first page. I already found this article: https://make.wordpress.org/core/2016/11/15/enhanced-pdf-support-4-7/

    I think, especially this part “The sizes generated can be modified, or the feature disabled entirely via the new fallback_intermediate_image_sizes filter, and are all stored in the sizes array in attachment meta.” refers to my problem.

    However, I don’t understand what is meant by filter and how can I exactly disable this feature.

    Hope you can help me. I appreciate it
