Fix Copy Exemplar Metadata

1) Localization text and ID were switched
2) Copying failed if image file was readonly
The old code is called twice.  I could inline it, but it would be duplicated.  

XIfItMakesSense does indeed indicate something may prevent us from even trying (no metadata, etc.).

Rather than AttemptToX, I could use XInner or DoX.  Am open to other suggestions.
