c# AgentGroupChat - how to pass image

[JP-droidic]

Hi team

is it possible to pass an image to group chat?

As far as I can see AgentGroupChat.AddChatMessage doesn't allow passing and ImageContent, I tried to trick it by passing:

chat.AddChatMessage(new ChatMessageContent(AuthorRole.User, $"![Image](data:image/png;base64,{base64Image})"));

but it doesn't work as I hit the token window

Basically, what I want to achieve is to make sure all the elements are correctly extracted from an Image, and I wanted to have two agents that will extract and verify extracted text

Yes you should be able to pass an image similarly to how you would pass chat. Tagging @crickman

You can specify image input for AgentGroupChat the same as for direct agent invocation.

Here's a sample: https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/GettingStartedWithAgents/OpenAIAssistant/Step02_Assistant_Vision.cs

Note: Not all models or agents support image input. For example, the Azure AI Agent is unable to currently accept image input.

For your example, I'd go with:

 chat.AddChatMessage(new ChatMessageContent(AuthorRole.User, [new ImageContent($"data:image/png;base64,{base64Image}")]);

I'll check back in for your response on how this goes.
