Resizing Pics to Match Matrix Size

[stevehoyt]

I started another thread regarding updating my matrix(s) in order to get better quality images. I will be going from 2 25H x 32W   to 1 50H x 48W and another 50H x 32W. 

I currently have a mishmash of 128  jpeg and gif files, that I have accumulated over the years.  No videos.

In the other thread, we discussed using Piskel and creating a matrix in Piskel  for each grid size.

So far just changing the preview definitions, and running my old shows the preview  appears much better. I won't see the real life effect until Nov when things get set up. 

So I am wondering about the best way to head, in setting up the files, for these new matrixes.

 Reszing them all could be a bit of work with 128 files.

So is it worth the effort to create 2 new copies of my old files in the new 2 newresolution or will the difference not be noticeable?

Thanks

Way back when... Paintshop Pro had a Batch mode.  Been a loooong time since I did any of that kind of thing.

Does any of the modern tools have a batch (bulk) mode?

(assumes resize can be set as a single target value)

OK, I just visited IRFanview home page and it says it does Batch Conversions
