Hi everyone,

I'd like to share with the community a collection of Python plugins I've developed for GIMP 3.0, specifically designed for photographers who publish on web platforms like Flickr and Instagram.

**MAIN FEATURES**

The suite includes 11 plugins that automate the entire photography workflow, from post-production to multi-format export. All plugins fully preserve EXIF metadata (camera, lens, shooting parameters, GPS, copyright) using the new GIMP 3.0 APIs.

**CORE PLUGINS**

1. **Interactive Process (FD)** - Most versatile
- Interactive processing with parameterizable GUI
- Complete pipeline: saturation, 1920px resize, NL edge enhancement, watermark, optional white border
- Adjustable parameters: saturation (0-100%), NL alpha/radius, border size
- Ideal for single image processing with full control

2. **Master Publish (FD)** - Batch automation
- Automatically processes all photos in a folder
- Dual output: Flickr (1920px) + Instagram (1080x1350px with blur background)
- Optimized pipeline for each platform
- Automatic suffixes: _1920_w.jpg and _1080_w.jpg

3. **Multi-Format Export (FD)** - Versatile export
- 6 preset formats: Web, Instagram Post/Stories, Thumbnail, Email, Print
- Format selection via GUI with checkboxes
- Optional watermark
- Batch processing with saturation and NL filter

4. **Publish 1920 + Watermark (FD)** - Three versions
- Hardcoded version: fixed parameters, fast
- JSON version: external configuration via file
- GUI version: graphical interface for all parameters

5. **1920 White Border (FD)** - Professional border
- Adds white border maintaining final 1920px size
- Customizable border size (default 90px)
- Integrated watermark

**TECHNICAL FEATURES**

- **Complete EXIF preservation**: all original metadata is maintained (camera, lens, ISO, aperture, GPS, copyright, ICC color profile)
- **Professional watermark**: semi-transparent white text with micro-shadow, adaptive size (2.7% of long side)
- **NL Edge Enhancement**: improves sharpness and details with configurable parameters
- **JPEG quality**: 95% for standard/print, 90% for web/social
- **Detailed logging**: log file for debugging and troubleshooting

**TYPICAL WORKFLOWS**

Workflow 1 - Flickr + Instagram Publishing:
- Put photos in ~/Pictures/FD_INPUT
- Run Master Publish (FD)
- Automatically get optimized versions for both platforms

Workflow 2 - Custom single image processing:
- Open photo in GIMP
- Run Interactive Process (FD)
- Adjust parameters in GUI
- Apply and export

Workflow 3 - Multi-format export:
- Batch processing with format selection
- Ideal for portfolios or multiple deliveries

**INSTALLATION**

Plugins should be copied to ~/Library/Application Support/GIMP/plugins/ (macOS) or the equivalent directory on Linux/Windows. Each plugin is a single executable .py file.

**COMPATIBILITY**

- GIMP 3.0 (uses new GObject Introspection APIs)
- Python 3.10+ (included in GIMP.app on macOS)
- GTK 3.0 for GUIs
- Tested on macOS, should work on Linux/Windows

**TECHNICAL NOTES**

On macOS, GTK windows may appear in the background: click the Python icon in the Dock to bring them to the foreground (system security limitation).

The NL filter (edge enhancement) is applied if available, otherwise it's skipped without errors.

**OPEN SOURCE CODE**

All scripts are available and can be customized. They use exclusively public GIMP 3.0 APIs and Python best practices.

**CONCLUSIONS**

This suite has transformed my photography workflow, reducing post-production time for web publishing from hours to minutes. I hope it can be useful to other photographers in the community as well.

I'm available for questions, suggestions, or collaborations to further improve the plugins.

Happy GIMPing!

Francesco

Looks like they might be handy.
Am I missing something, I cannot see where you added the plugins or a link to them? Also are they free?

Can't see them either.

So far they are in my own availability. The aim of the message is that thank to some AI tool it is possible to generate something very useful for not IT professional.

Then don't write

You are right, could you suggest a way to share them here?

Zip pack and attach here?

Ok, I follow the suggestion and share with this community my scripts.
They are for GIMP 3.2.4 on Mac.
Please feel free to comment them

Thank you.
They won't work on anybody else's system because of hardcoded paths.
To begin with: a normal shebang (First line) looks like this:
#!/usr/bin/env python ...

Thanks
Ok but anyone could see them and take ideas for own needs or adapt to the used machine. My actual aim, I repeat, was to share the thing that also who has not great competencies on Python could take advantage with the help of an AI tool.

@ quietreader, it is unusual to get things made just for Mac. What a victory for them. Windows users especially are privelidged as we get the most. There may be someone here who can change the inners to get them working for windows and linux.

You have my admiration for at least creating the plugins - there will be people who will put them down as AI generated rubbish code. you do better than me, only managed a couple of simple script-fu utilities for my own use.

I only looked at one plugin, guessed it might be simple to adjust, the watermark plugin.

As quitereader: the script starts with a shebag #!/usr/bin/env python3 and as a plugin has to go in its own folder, fd-watermark.py goes in a folder fd-watermark The plugin fd-watermark.py marked executable. You can change the name at line 75 and 84 and probably get rid of the log file section. Some text properties as well.

...and it works, a quick test and seems to scale ok acording to size of image. Looks like this.

Thanks for the review.
Obviously you can change all the private customization.
Please let me know better what you mean about the shebang, isn't it correct by your point of view?

The shebang #!/usr/bin/env python3 tells the program (Gimp 3) which interpreter to use.

You are using #!/Users/francescodini/.local/bin/gimp-python3 Not going to work with anything other than your installation.

There are a few python plugins that come with Gimp 3 Does the spirogimp plugin work with your installation. Filters -> Render -> Spirogimp That uses the regular shebang. Example in a Win11 installation.

Many thanks for your suggestion, I put the question to the AI tool, it corrected every script. Here below its comment:

**SOLVED! Thank you for the help!**

You were absolutely right about the shebang issue. I checked the spirogimp plugin as you suggested, and it uses `#!/usr/bin/env python3` as the shebang.

**The Problem:**
I was using `#!/Users/francescodini/.local/bin/gimp-python3` which was specific to my installation path and wouldn't work on other systems or with GIMP's standard Python interpreter.

**The Solution:**
I changed all my plugins to use the standard shebang:
```python
#!/usr/bin/env python3
```

**Result:**
✅ All plugins now work correctly with GIMP 3!
✅ Tested 3 plugins and they all function properly
✅ The standard shebang ensures compatibility across different systems

Thank you for pointing me to the spirogimp example - it was exactly what I needed to understand the correct configuration!

New version of the script attached as suggested by rich2005

So I'm guessing it can be used in Windows now? If so, is the folder that is named MAC needed?
What is the menu?
Where can it be found?
I looked through everything but didn't see it, after restarting gimp. If the computer needs to restart I will have another look tomorrow.

Open a .py file with an editor and search for
menu_label which is the name of the script in the menu
and menu_path which tells you where to look for it in your GIMP.
In this case : ("<Image>/Filters/FD_plugin"). So Filters > FD_plugin is what you are looking for.
The MACOSX folder is not needed
