A couple of tips for anyone getting started with I-View (I've been using it for years and love it).
Be sure and download the filters or plugins along with the program.
You can go to any directory (folder) and open the first image and then hit the "t" key and it will open thumbnails of all images in the directory. These are temporary files and are not written to your drive so the don't clutter things up and leave a bunch of files laying around.
When doing resizing use resample and not resize. You get a better image and I have found if you go into advanced and check sharpen and set it to about 5 it will clean things up from the resample.
It has a lossless rotation that does a great job.
The program will read the EXIF info for a file by hitting the "i" key with an image open and will also save that info if you alter an image and resave it with the same or a different file name.
Hitting the enter key will give you full screen view of a large image.
Space and backspace will move you through the images in a directory.
I'll shut up now.
