XnView Software

Thanks Pierre!

It worked from command line (I had to rearrange it a little, though):
nconvert -ratio -rtype linear -resize 800 600 -out jpeg -o $results/%_800x600 file.jpg

But I still can't make it work as part of a batch file. It resizes to "results" folder but doesn't add "_800x600" suffix ...

Sorry, but I couldn't figure out how to do that with NConvert :(
I searched this forum but to no success.
I've read Usage.txt but sample codes didn't work for me

Could you please give me a working code for my case?

I convert a lot of pictures at once.
1. resize to 800x600 to "results" folder;
2. rename result files (add "_800x600" to their filenames);
3. resize initial files to 150x150 to ...
