Hi @Luigi_Giugliano, welcome to the forum!
This question is pretty broad, and it would be helpful to know more information about the issue you’re facing. For example:
- Where are you hoping to save the picture?
- What have you tried so far that hasn’t worked?
- Have you read through the streamlit docs to discover things like st.file_uploader and st.image?
If you could read through this post Using Streamlit: how to post a question in the Streamlit forum and add some more details to your question (if reading the docs and other forum posts doesn’t answer your question), that would be helpful.
