Improve download btn functionality

[andimg93]

Right now the download button only works for specific cases - Meta data (content-disposition) is related to an attachment, etc. .

Why not improving that functionality by just forcing the download based on the related image url, like:

fetch(url).then(res => res.blob()).then(file => {
    let tmpUrl = URL.createObjectURL(file);
    const aTag = document.createElement("a");
    aTag.href = tmpUrl;
    aTag.download = url.replace(/^.*[\\\/]/, '');
    document.body.appendChild(aTag);
    aTag.click();
    URL.revokeObjectURL(tmpUrl);
    aTag.remove();
}).catch(() => {
    alert("Failed to download file!");
});

Something like that will always work, so also for an image url like this one:
