| ### User function | |
| The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both). | |
| - When used as an Input, the component only impacts the input signature of the user function. | |
| - When used as an output, the component only impacts the return signature of the user function. | |
| The code snippet below is accurate in cases where the component is used as both an input and an output. | |
| - **As output:** Should return, list of images, or list of (image, caption) tuples. | |
