What worked for me was to create the image in a drawing app (I used Snaggit). Save the image as a png. That image if used as a launch screen for my iPad app did not work it was stretched or it showed as a white black split screen. Save it somewhere so the iPad can get to it. Show it on the iPad. Then take a screen grab on the iPad. I could then edit that image in Snaggit and it consistently displayed as a launch screen after that. This may not work for you but it has consistently worked for me. good luck.
