Question to fallback images and other

    Hello, sorry, I do not understand totally this option:

    “Also generate fallback images in the original upload format – Enabling fallback image output can improve compatibility, but will increase the filesystem storage use of your images.”

    Does this mean, without this function enabled – the original/uploaded jpg-image will be deleted? Or what is meant by “generating an image in the original upload format”? This original image is already there with the upload, no?

    Furthermore I have a question for the bulk exchange via image regenrating. How will the posts with the original jpg-images then know that they shall save the webp-version now? Or, will the filename just stay the same (jpg), but indeed BE an webp then?

    And third: what happens to alt-texts etc.? Will they be safely kept?

    Thank you very much!
    Sandra

    I think this paragraph from the readme answers your first question:

    By default, only modern image format sub-sizes will be generated for JPEG or PNG uploads – only the original uploaded file will still exist as a JPEG/PNG image, generated image sizes will be WebP or AVIF files. To change this behavior, there is a checkbox in Settings > Media “Output fallback images” that – when checked – will result in the plugin generating both the original format as well as WebP or AVIF images for every sub-size (noting again that this will only affect newly uploaded images, i.e. after making said change).

    So the this is about the format(s) used when the subsizes are created.

    In regards to your second question: the original JPEG is kept as the image referenced in the posts. It’s only when the post is rendered on the frontend that the WebP/AVIF version is used instead, when the plugin is active.

    The alt text remains unchanged.

    I am not the primary developer of this plugin, but these are the best answers I have given my familiarity.
