Saving jpeg data

Subject: Saving jpeg data

My application now saves jpeg thumbnail data from an NSImage of a bit map by using

      [NSBitmapImageRep representationUsingType:properties]

selector and it works fine in Snow Leopard development. When I run the app in Tiger, however, the code fails with following selector problem in the Console:

2010-03-30 13:03:24.689 GEDitCOM II[631] start saving file at 2010-03-30 13:03:24 -0700 2010-03-30 13:03:26.738 GEDitCOM II[631] *** -[NSCachedImageRep representationUsingType:properties:]: selector not recognized [self = 0x930a8c0]

I checked and [NSBitmapImageRep representationUsingType:properties] has been available since 10.0. I don't know what NSCachedImageRep is and I did not think I created or accessed one either?
