"Could not copy splash"

[Mike Kerner]

So I was messing with a new ios app today.  I created a really simple
splash screen, but when I try to create the standalone, I get an error
"Could not copy splash" (and the path of the .png for the splash screen.

If I double-click on the file, it opens just fine, so any ideas on what
this might be?

On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
