Batch Processing on Mac

[Gimpah]

I need some guidance on how to do batch processing (for now just resizing a set of photographs). 

I am on Mac - Catalina 10.15.5 , GIMP version 2.10.

Based on my research a common plugin for batch precessing is called BIMP.

Their web site says:

"There's no need to install or compile BIMP on Mac, because the default native build of GIMP for Mac OSX 10.8 made by Simone from http://gimp.lisanet.de/Website/Download.html already includes BIMP!" 

But that link there is broken.

Can someone pls help?

Thx

p.s.

I have found some instruction here:

https://github.com/alessandrofrancesconi...lugin-bimp

but to be honest can't follow them. I am hoping there is a n easier way!

You will be lucky

First the macos problem.  The lisanet versions ended 2017 with a Gimp 2.8 Still available https://sourceforge.net/projects/gimponosx/files/ but I have no idea if BIMP is included in all of the versions.


At the moment BIMP is the only Gimp batch processor plugin for users who do not use scripting languages. (There is an ancient plugin DBP but never updated beyond Gimp 2.4)

You might be able to compile your own plugin, I found this https://community.gamedev.tv/t/getting-g...acos/36089 

Very few macos users visit this forum to give advice. There are some on https://discuss.pixls.us/ Ask the question there for advice on compiling. Problem is that forum is swamped by other applications and Gimp questions tend to get lost.

The usual advice from the experts is use a gimp command wrapped up in batch file. 
https://www.gimp.org/tutorials/Basic_Batch  ( Wonderful, refers to Gimp 2.4 and still reads like sanskrit to me but that is what you do.)

Alternatives. 

Imagemagick https://imagemagick.org/index.php  This is command line. there is extensive documentation but generally you need to write your own scripts.
However there is a collection of scripts for macos/linux - this for resizing http://www.fmwconcepts.com/imagemagick/aspect/index.php  You will still need to wrap that up for batch processing.

XnViewMP - for those of us who like a GUI https://newsgroup.xnview.com/viewtopic.php?f=82&t=40646 there is a 64 bit mac version. Might work and also check out the older versions.

best of luck.

Thank you kindly Rich2005 for your thorough reply.

It sounds I am out of luck since I am just an average user (who feels below average now since I don't even know what "compile your own plugin"  and "wrap that up.." means.

Before my original post, I tried to follow that advice from gamedev (you linked) a few times to no avail.

It seems I need to go get a degree in programming/compuetr science and come back before I can edit images!

Thanks again for your time.
