How to fix an error with images when deploying my streamlit webapp?

Question

I started by making a text file (requirements.txt) with all the versions of the libraries used in the code. So I opened a folder on GitHub and added all the necessary files.

I used Streamlit Sharing to deploy and it returned the following error:

File "/home/appuser/venv/lib/python3.7/site-packages/streamlit/script_runner.py", line 379, in _run_script
    exec(code, module.__dict__)
File "/app/orbitas-relativistics/webapp.py", line 15, in <module>
    image1 = Image.open(r'C:/Users/isabe/.streamlit/titulo11.png')
File "/home/appuser/venv/lib/python3.7/site-packages/PIL/Image.py", line 2953, in open
    fp = builtins.open(filename, "rb")

My code doesn't have the command fp = builtins.open(filename, "rb") and it doesn't even have 2953 lines. It only has 395.

About the images, I uploaded them inside the .streamlit folder of my Visual Studio Code (where the code is hosted). And it gives the error

FileNotFoundError: [Errno 2] No such file or directory: 'C:/Users/isabe/.streamlit/titulo11.png'

Does anyone know what I should do to fix this error and proceed with the deployment of my site?

Thanks for any help.
