This allows editors to generate AI-generated images directly in the TYPO3 backend. This works using Google Gemini (with Nano Banana).
- To use the extension, you need a Google Gemini API key. You can register for one at https://aistudio.google.com/app/api-keys.
- Look at https://ai.google.dev/gemini-api/docs/image-generation?hl=de#rest_22 for example prompts and to learn more about the power of Gemini image creation
composer req in2code/imager
After that, you have to set some initial configuration in Extension Manager configuration:
| Title | Default value | Description |
|---|---|---|
| promptPlaceholder | LLL:EXT:imager/Resources/Private/Language/Backend/locallang.xlf:prompt.placeholder | LLL path to a label for placeholder for prompt field in backend |
| promptValue | LLL:EXT:imager/Resources/Private/Language/Backend/locallang.xlf:prompt.value | LLL path for a default value for prompt field in backend |
| promptPrefix | - | Prefix text that should be always added to the prompt at the beginning |
| combinedIdentifier | 1:/_imager/ | Define where to store new ai generated images |
| aspectRatio | 16:9 | Default ratio for new ai images. Must be one of this values: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 |
| model | 3_pro_image_preview | Select a Gemini model (prices in Gemini may differ on different models) |
| apiKey | - | Google Gemini API key. You can let this value empty and simply use ENV_VAR "GOOGLE_API_KEY" instead if you want to use CI pipelines for this setting |
Note: It's recommended to use ENV vars for in2code/imager instead of saving the API-Key in Extension Manager configuration
GOOGLE_API_KEY=your_api_key_from_google
There are some events in EXT:imager that can be used to
- Decide to hide the button in backend (\In2code\Imager\Events\ButtonAllowedEvent::class)
- Manipulate or overrule the template of the rendered button in backend (\In2code\Imager\Events\TemplateButtonEvent::class)
- Manipulte the URL and request values before sending to Gemini (\In2code\Imager\Events\BeforeRequestEvent::class)
