Unfortunately I have yet to get the ECW SDK to work on OS X.  You  
need the current 3.3 version for Tiger/GCC 4 support, I think.   
Supposedly reading will work, but I can't even get that to work.   
Writing has threading issues.  I patiently wait...

But, the free version should be able to read any size images.  Maybe  
the older versions were limited to 500MB.  The licensing was changed  
recently for a more open source-friendly free version.
