Banana Imagine – AI Image Generation via Google Nano Banana

[maximus]

Hi everyone,

I'd like to introduce Banana Imagine — a ProcessWire module that brings high-quality AI image generation directly into your image fields using the Google Nano Banana API.

Key features:

• Clean generation interface right below supported image fields
• Generate 1–4 variations at once
• Smart subtle prompt variations for better batch diversity
• Selected images saved natively to the page (with clean naming: [pageID]-[timestamp].jpg)
• Simple configuration: API key + choose which image fields to enable

This module is a fork / spiritual successor to my previous module GrokImagine (xAI/Grok-based):
https://processwire.com/talk/topic/31744-grokimagine-ai-image-generation-via-xai/

Installation & usage instructions are in the README:
Just drop the folder into /site/modules/, install, add your Google AI API key (billing required for image gen), select fields → you're good to go.

Screenshots:

Feedback, bug reports, and feature ideas are very welcome!

Thanks,
Maxim

Hi @maximus

I use your great Module in a RepeaterMatrix Profield Image. The BananaImage Bar didn`t show up in the RepeaterMatrix. It´s because auf the dynamic name-Field of the image field in the Repeater.
Here is a fix suggestion for the BananaImagine.module.php:

if(!in_array($inputfield->name, $useFields)) return;

updated
$trueFieldName = preg_replace('/_repeater\d+$/', '', $inputfield->name);
if(!in_array($trueFieldName, $useFields)) return;

This would make the module useable in RepeaterMatrix ProFields.

Hi Jochen,

thank you for the report and the fix — you were absolutely right about the dynamic RepeaterMatrix field name. I've applied the normalization and pushed it to main. Banana Imagine now recognizes enabled image fields inside RepeaterMatrix items.

I also used the opportunity to publish a small 1.1.1 update:

- the default model is now Gemini 3.1 Flash Image (Nano Banana 2)
- added Gemini 3.1 Flash Lite Image, stable Gemini 3 Pro Image, and kept Gemini 2.5 Flash Image
- old gemini-3-pro-image-preview settings migrate automatically
- refreshed the README and added an AI/Olivia-friendly AGENTS.md plus a new project illustration

The same RepeaterMatrix fix was applied to GrokImagine too.

Thanks again for taking the time to track this down and share the patch!
