Important: Make sure function calling is enabled in SillyTavern's AI settings and the model you're using supports function calling.

In SillyTavern's AI settings, verify that:

1. Function calling is enabled
2. "Include functions in context" is checked
3. The function appears in the function list

🚨 REQUIRED SETUP: You MUST add the following to your system prompt or character card:

You have access to a function called generateChatBubbleImage(text, style) that creates chat bubbles with the given text.

The function parameters are:
- text: The text to display in the chat bubble (required string)
- style: Visual style of the bubble (optional string: "default", "modern", "retro", or "minimal")

When you want to create a chat bubble, call this function with the text you want to display.
Example usage:
generateChatBubbleImage("Hello world!")
generateChatBubbleImage("Hello in retro style", "retro")

ALTERNATIVE: If the AI can't call the function directly, you can instruct it to respond with Markdown formatted like this:

![](image.php?q=Hello%20world)
