Batch processing on an iMAC

Hi:

I need to process upward of 700 pictures through GIMP with a simple workflow:

- Open a picture file - Export it as a JPG file

which enables these files to be uploaded in a custom database (programmed with Cold Fusion - not by me!) which only accepts the JPG format.

Can anybody give me some ideas or a script to do that?

GIMP is not scriptable with the MAC Script Editor, and it seems only some Unix-level commands using the Terminal app will work.

Thanks in advance, as this would save me a lot of hours doing this manually!

If I had to do this? Not Gimp, use ImageMagick. see https://www.imagemagick.org/script/download.php

Can be a simple as.

magick mogrify -format jpg *.png

will convert a folder full of png images to jpegs.

On the other hand, if you want to see each image before exporting, the attached rough-n-ready script exports to a 90 quality jpeg. You need to specify the destination but only once per session. Unzip, pop in your plugins folder (it is python) check that it is executable.

Thank you very much...
I may try your suggestion.

I still advise ImageMagick for 700 files however as a demo two scripts *****.scm which go in your Gimp profile scripts folder (no need to make these executable)

sg-sequential-edit.scm and quick-export-jpeg.scm zipped them both up and attached.

A quick video demo of these in use with keyboard shortcuts which reduces open-export-close to two key presses.
