Re: [Openexr-devel] New images available for download

[Drew Hess]

p.s. as I indicated in an email last week, you will only need to relink 
your code against the new OpenEXR libraries to read the tiled files.  You 
don't need to make changes to your source code unless you want to take 
advantage of the ability to read tiles, mip/ripmap levels, etc.
