When run from Docker - Fatal error: Uncaught Intervention\Image\Exception\NotReadableException: Unable to init from given binary data about hot-this-week

This might be the reason why it's happening, but I'm still only experiencing this in Docker only.

There's this function in vendor/intervention/image/src/Intervention/Image/Gd/Decoder.php:

/**
     * Initiates new image from binary data
     *
     * @param  string $data
     * @return \Intervention\Image\Image
     */
    public function initFromBinary($binary)
    {
        $resource = @imagecreatefromstring($binary);

        if ($resource === false) {
             throw new NotReadableException(
                "Unable to init from given binary data."
            );
        }

        $image = $this->initFromGdResource($resource);
        $image->mime = finfo_buffer(finfo_open(FILEINFO_MIME_TYPE), $binary);

        return $image;
    }

imagecreatefromstring appears to be returning false on webp in my Docker image. This implies a problem with the libgd library provided with the underlying container OS than a problem with the code itself.

I've replaced the Docker build with CentOS 7. Rather a dramatic change, but since I'm (at least now) the only user and the mainline PHP build has problems I can use that + remirepo from familiarity.

This now works on Intel/AMD. Yet to test on ARM, but issue can be closed for now.
