Hi, thanks for your great work. When I click the button "Paste an image", the following bug always occurs. Do you know why? Thank you.

Hi Zixu,

I hope this helps:

i took https://github.com/streamlit/streamlit-example

Then added:

`from streamlit_paste_button import paste_image_button as pbutton
...
paste_result = pbutton("paste image", text_color="#1c2c5e", background_color="#fafcfd", hover_background_color="#deefff", errors="raise")

            if paste_result.image_data is not None:
                image_data = paste_result.image_data.tobytes()
                image_hash = hashlib.md5(image_data).hexdigest()`

This only works in https sessions due to browser security reasons.

Firefox users may need to modify the asyncClipboard in the about:config. Please take this with a grain of salt.
