Image minimum is 1024x768, but no matter what you've been told, bigger is better.
Is your image vertically orientated? (a phone wallpaper?) You're looking for /r/lewd_phone_wallpapers
Reposting from /r/gonewild or similar reddits without permission gets your post removed. Repeat offenders will be banned. This is your only warning.
NSFW posts only, please. If you wouldn't get in trouble with your boss over it, it goes over in /r/wallpapers
If you like your thumbnails big(er), then ReddPics is a nice way to browse.
