## Installation

```bash
pip install gradio_imagefeed

## Usage

```python

import gradio as gr
from gradio_imagefeed import ImageFeed
import time
from PIL import Image, ImageFilter
import os 

image = Image.open(os.path.join(os.path.dirname(__file__), "butterfly.png"))

def fake_unblur(steps=5):
    for i in range(steps):
        yield blurred_images[i]
        time.sleep(1)
    yield image

with gr.Blocks() as demo: 
    with gr.Row():
        imagefeed = ImageFeed(label="Generated Images")
    button = gr.Button("Start Generating")
    button.click(fake_unblur, inputs=None, outputs=imagefeed)

### 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.

    value: np.ndarray | _Image.Image | str | None
) -> np.ndarray | _Image.Image | str | Path | None:
