IOS launch images - driving me crazy

Although not pretty I use this quick way

1. Create a new LaunchImage and drop any file onto each box
2. Build it , it will fail or have some warnings
3. Click on the "Show Report navigator" and you'll see the sizes/names for each
4. On your image editor resize the image to the proper sizes/names and overwrite to
the respective file as reported in 3. each file is on 
<proj dir>/Assets.xcassets/LaunchImage.launchImage

Do the same for icons and don't look back

For anyone finding this now i've created a list to simply explain what each of Apple's somewhat confusing names actually mean.
