======** unableToReadImageError**======
#define unableToReadImageError()		error("Read failed or premature end of image file")

**Parms**: NONE
**return**: NONE, fake return of zero
**From**: Interpreter
**Why**: 
error feedback if the image cannot be read

**Responsibility**:
When we issue the sqImageFileRead we check the bytes read versus the request, if they are not equal then we fail with this error

**MacIntosh**
//os-9/OSXCarbon//
  #define unableToReadImageError() plugInNotifyUser("Read failed or premature end of image file")

//Cocoa://
See iPHone

**iPhone**
  #define unableToReadImageError() plugInNotifyUser("Read failed or premature end of image file")

**Unix**

**Windows**

**BUGS**
Macintosh and iPhone using new mmap logic don't check to see if the file size is the same as the dataSize - (headerStart+headerSize) to 
ensure the amount of bytes we think we are going to read is the same as contained in the file.   Note dataSize comes from image header.
