I just wanted to chime in and also recommend ImageNest. I stopped using Qimage since the 3.0 version of Imagenest came out. The new version they are working on will have print sharpening built in along with many other options.
I used Qimage on the PC, before moving to a Mac, and I've really missed it's conveniences. I tried running it under Parallels a few years ago and was not successful. However, I would much prefer something native to the Mac.
I'm encouraged to hear that Imagenest is getting resizing and output sharpening. The lack of those features has kept me from making a purchase in the past. Having said that, does Lightroom really do all the Imagenest does (or is about to do), and more?
Terry.
