Hi @Julie_GA
For a super crisp resolution, you can use the SVG version of the image. The image SVG URL was found on the website (https://executive-education.minesparis.psl.eu/) to be https://executive-education.minesparis.psl.eu/wp-content/themes/psl/images/logo-header.svg
Here’s a simple way to display this via st.markdown and HTML:
with st.sidebar:
st.markdown('''
<img src="https://executive-education.minesparis.psl.eu/wp-content/themes/psl/images/logo-header.svg">
''', unsafe_allow_html=True)
As it’s a vector image it does not pixelate when zoomed in:
If you’d like to use a local SVG image, you can implement what is mentioned in this post (Display SVG).
Hope this helps!
