    <source data-srcset="./../../Images/placeholder_topic.webp" srcset="./../../Images/placeholder_topic.webp">
    <img class=" lazyloaded" alt="placeholder_topic.png" data-src="../../Images/placeholder_topic.jpg" src="../../Images/placeholder_topic.jpg">
</picture>

HTTrack cannot parse the "source" tag, so the image "placeholder_topic.webp" will not be downloaded.
