## Methods

### <a id="Tracon_GoogleImageBuilderExtensions_UseGoogleImages_Tracon_ITraconBuilder_System_Action_Tracon_TraconImageOptions__"></a> UseGoogleImages\(ITraconBuilder, Action<TraconImageOptions\>?\)

Registers the Google image generator.

```csharp
public static ITraconBuilder UseGoogleImages(this ITraconBuilder builder, Action<TraconImageOptions>? configure = null)
```

#### Parameters

`builder` [ITraconBuilder](/api/tracon.itraconbuilder/)

The Tracon chain.

`configure` [Action](https://learn.microsoft.com/dotnet/api/system.action\-1)<[TraconImageOptions](/api/tracon.traconimageoptions/)\>?

Optional image-tool settings.

#### Returns

 [ITraconBuilder](/api/tracon.itraconbuilder/)

The continuation of the chain.

#### Remarks

Call [GoogleProviderExtensions.UseGoogle](/api/tracon.googleproviderextensions/)
first. Google.GenAI has no Microsoft.Extensions.AI image adapter, so this
call registers Tracon's narrow GenerateAsync-only adapter.

**The model must be one that generates images through
`generateContent`**, such as a Gemini image model. The older
Imagen `predict` surface is not served by the Gemini API and a
model that only supports it fails every request.

The adapter generates from a prompt only. `Count` is passed as the
candidate count and an image model commonly returns one image whatever
you ask for. A requested media type is passed to the model and the
answer is *checked*: if the model returns another format the call
fails rather than handing back bytes that do not match what was asked
for. Omit it to accept the model's own choice.

```csharp
builder.AddTracon()
       .UseGoogle(builder.Configuration["Google:ApiKey"]!)
       .UseGoogleImages(options =>
       {
           options.Enabled = true;
           options.Model = "gemini-2.5-flash-image";
       });
```
