Dream Prompter: Bringing Nano Banana to Gimp (thoughts.greyh.at)

Dream Prompter is a new GIMP plugin that embeds Google’s Gemini 2.5 Flash Image Preview model (aka “Nano Banana”) directly into the GIMP workflow, letting you generate or edit images with natural-language prompts without leaving the editor. Built by a developer new to GIMP/Python with substantial assistance from Claude, the plugin creates non-destructive results as new, descriptively named layers, supports up to 3 reference images for generation (2 for editing plus the current image), and includes multi-language UI (11 languages). The interface sits under Filters → AI → Dream Prompter and provides progress updates while running background, non-blocking API calls so the UI stays responsive. This matters because it removes the clunky context-switching between design apps and web generators, making AI a native tool in creative workflows. Technically, Dream Prompter uses Google’s Gemini API (paid tier required), respects Gemini limits (7 MB per image, PNG/JPEG/WebP only, attachment caps), and depends on GIMP 3.0.x and the google-genai Python library. The code is modular (separate files for API integration, GTK UI, threading, GIMP integration, settings, i18n), was put together quickly, and is available on GitHub (with an AUR package). Limitations include required billing and file/format constraints; the project is open to contributors for testing, docs, features and translations.
