Instead of having to pick a resolution in the select box for each and every wallpaper, this script adds new button(s) with a direct link to a selection of favourite resolutions for this picture.
You can right click and "save target as...", or just click and it will open the wallpaper in a new tab/window.
Hardcoded resolutions are: 1024x768 (15"), 1280x1024 (17/19"), 2560x1024 (dual 17/19").
Just edit the res array in the script to add/remove resolutions (provided they exist on InterfaceLift or you'll get a 404 error when trying to download).
Enjoy!
