st.column_config.ImageColumn

Configure an image column in st.dataframe or st.data_editor.

The cell values need to be one of:

  • A URL to fetch the image from. This can also be a relative URL of an image deployed via static file serving. Note that you can NOT use an arbitrary local image if it is not available through a public URL.
  • A data URL containing an SVG XML like data:image/svg+xml;utf8,<svg xmlns=...</svg>.
  • A data URL containing a Base64 encoded image like data:image/png;base64,iVBO....

Image columns are not editable at the moment. This command needs to be used in the column_config parameter of st.dataframe or st.data_editor.

Function signature[source]

st.column_config.ImageColumn(label=None, *, width=None, help=None, pinned=None)

Parameters

label (str or None)

The label shown at the top of the column. If this is None (default), the column name is used.

width ("small", "medium", "large", or None)

The display width of the column. If this is None (default), the column will be sized to fit the cell contents. Otherwise, this can be one of the following:

  • "small": 75px wide
  • "medium": 200px wide
  • "large": 400px wide

help (str or None)

A tooltip that gets displayed when hovering over the column label. If this is None (default), no tooltip is displayed.

The tooltip can optionally contain GitHub-flavored Markdown, including the Markdown directives described in the body parameter of st.markdown.

pinned (bool or None)

Whether the column is pinned. A pinned column will stay visible on the left side no matter where the user scrolls. If this is None (default), Streamlit will decide: index columns are pinned, and data columns are not pinned.
