I have a link_to Rails helper that downloads a wallpaper when clicked. But the image is loading in the browser instead of being downloaded immediately.

<%= link_to "1920x1080", @download.wallpapers[1].wallpaper.url %>

But at the same time I have a link_to Rails helper that downloads a screensaver of .exe format but here it works as inteded: file being downloaded immediately.

<%= link_to "720p", @download.screensavers.first.screensaver.url %>

What should I add or do so that the images will not be opened in the browser but instead be downloaded immediately?

Thanks!

There is an easier way to do this with the HTML5 download attribute.

<%= link_to 'Download existing avatar', @user.avatar(:original), download: "User_#{@user.id}_avatar" %>
