Fixing image within a TAB in place while scrolling

I have an image and a graph side by side within a tab.
The graph can have a lot of subplots, resulting in the image not being on the display anymore,
when i look at the lower subplots.
How can i fix the image in place during scrolling?

    dcc.Tabs(id='tabs', children=[
             dcc.Tab(label='Table', 
                     children= [html.Table(id='output-data-upload')]),    #calling the table
                             
             dcc.Tab(label='Graph',
                     #calling the graph 
                     children= [html.Div([
                                     
                                     html.Div([dcc.Graph(id='migration_data'),
                                               #MD.save_button()
                                               ],
                                          className= 'six columns'),
                                     html.Div([html.Img(id='image-overlay',
                                                        style={
                                                            'height': '75%',
                                                            'width': '75%',
                                                            'float': 'right',
                                                            'position': 'relative',
                                                            'margin-top': 20,
                                                            'margin-right': 20
                                                                }),],
                                          className='six columns'),
                                               
                                 ], className='row')]
                                 
                     )
            ]),

I tried to set the style argument of the image to {‘position’:‘fixed’}. which just results in the image not being there at all. I tried to set the style argument of the Div, that holds the image to {‘position’:‘fixed’}, but that resulted in the image being in the center of the lower edge of the screen, which 90% of its content outside the screen.
If I add the style argument ‘top’:0 it is displayed but outside of the tab.
To be clear: It is only displayed when the tab is active, but I do have items that do not belong to any tab above my tabs, and it is not displayed in the section of the tab, but above it.


How can I maintain it within the tab at a fixed position?
