Guys, stop attaching shit if it's obvious it will resize everything. Use
http://imgur.com, there are browser extensions and other software to make uploading there as painless as possible =>
http://imgur.com/apps
You can use the tags {url=www.imgur.jpg}{img}www.imgurl.jpg{/img}{/url}. Replace { with [. Notice the "L" added at the end of the second link. That links to a lower size Thumbnail so you don't rape everyone with a lower res screen but when clicked it will open the full size version.
Also, I don't think the point of this thread is to dump everything you have on your harddrive,
http://wallbase.ru/can provide massive amounts. I like to think people will post here their current and/or "look what I found" wallpapers.
