I want to send somebody small size samples of 200 vacation pictures, say 500-1000 pixels wide instead of 7,000 pixels wide. View NX can shrink when exporting JPEG. Some of my files were edited with Capture NX 2 so View NX refuses to export them. I need to use Capture NX 2. Capture does not have a shrink option in the export menu. The quality option isn't good enough. Even "highest compression ratio" aka quality 10 makes the files 2-3 megabytes. (A bug?) I'm not going to risk doing a batch scale operation (even if I could find the menu for it) because it would probably save the change permanently.

What's my best option?

Plan B is export them all huge and run a separate tool to shrink the pixel size of the files. djpeg|pnmscale|cjpeg on Unix will do it.
