MSPaint thumbnail snippet

[beernuts]

This code takes the file and pathname from edit1 infobox in my GUI and sends it to MSpaint to make a thumbnail 200 pixels high and saves that thumbnail in the same place as the original file but rewrites the file name to include "_thumb.jpg" There's a tiny bit of math in it to maintain the correct aspect ratio allthough sometimes the picture will be cropped a tiny bit, 2 pixels max. If you want the height to be different than 200 you could call another value from your GUI or change the value in $heightfixer in the code.

You can do this much more elegant way:

use IrFanView and it's commnadline
