download image shortcut

im sorry if there's already topic of this but
have been wondering if there's any plan to make a shortcut to download an image [original size] by using keyboard button such as shift + D or anything else

This seems impossible to do through JavaScript alone - https://stackoverflow.com/questions/5192917/force-download-through-js-or-query

Hotkey to open a full-size image in a new tab is one thing, but forcing the browser to immediately download it would require server-side page dedicated to this purpose.

It is possible with JavaScript alone (and the help of the HTML5 download attribute):

download = document.createElement("a");
download.setAttribute("download","");
download.setAttribute("href","https://danbooru.donmai.us/data/a68430f82f2877b1eb43a9abed73e6fa.png");
download.setAttribute("style","display:none");
document.body.appendChild(download).click();

Some notes:

• This is tested with Firefox and should work with Chrome and Edge as well but it won't work with IE
• In Firefox this works only for same-origin downloads - not a problem in this case -
• For the JavaScript generated click to work the element has to be inserted into the DOM, but it can be invisble

Of course the above code would have to be either added as site feature or adapted into an userscript.

Yep, this wouldn't work on certain browsers, so it's probably better to make it a userscript instead.

The Download button in the sidebar has that attribute already, though unfortunately it doesn't have a giveaway id or class.

document.querySelector('a[download][href^="/data/"]').click();
