Improvements

What is the difference between this repo and robmarkcole's?

• This is a pypi installable package
• This does not require the images to be saved under site-packages/streamlit/static/
• This accepts any type of image as input (doesn't have to be present in local)
• This can utilize all parameters of the JS component
• This has an additional dependency sahi
