Image added to figure not included when figure to PNG or SVG :/

[nolefp]

HI - I have an issue where I include an image (logo) in my plotly chart, it displays in my jupyter notebook fine, but it does not get included when I export the figure to png??? What is going on??

THank you!!

code below:

ymax = 0.6
ymin = 0
xmax = 30000
xmin = 0

# filter dataset (remove outliers)
df = cossdf[(cossdf.stargazers_count > xmin) & 
            (cossdf.stargazers_count < xmax) & 
            (cossdf.stars_growth6m < ymax) &
            (cossdf.cat2 == 'data')].copy()


keep_list = []

def keep(dff):
    if (dff['stars_growth6m'] > 0.1) & ((dff['stargazers_count'] > 5000)):
        return dff['url_shortest']
    elif (dff['stars_growth6m'] > 0.17) & ((dff['stargazers_count'] > 0)):
        return dff['url_shortest']
    elif (dff['stars_growth6m'] > 0.05) & ((dff['stargazers_count'] > 15000)):
        return dff['url_shortest']
    else:
        return ''
df.stars_growth6m
df['url_shortest'] = df.apply(keep, axis=1)

        
fig = px.scatter(df, x="stargazers_count", y=df.stars_growth6m.astype('float'),
                trendline="ols",
                trendline_options=dict(log_x=True),
                trendline_scope = 'overall',
                text='url_shortest',
                hover_data=["url_short"],
                color=df.COSS.fillna('-'),
                opacity=0.5,
                color_discrete_sequence=px.colors.qualitative.Bold
                )

fig.update_layout(yaxis_title="6 Month Growth Rate",
                  xaxis_title="Total Stargazers",
                  yaxis_tickformat=',.0%')

fig.update_traces(textposition='top right')

fig.add_layout_image(
    dict(
        source='media/rajko_sig4.svg',
        xref="paper", yref="paper",
        x=.67, y=.9,
        sizex=0.3, sizey=0.8,
        sizing = 'contain',
        xanchor="left", yanchor="bottom"))

fig.update_layout(title={
       'text': 'Total Stargazers vs. 6 Month Growth Rate - (Data only)',
        'y':0.9,
        'x':0.5,
        'xanchor': 'center',
        'yanchor': 'top'}, width=1500, height=1200, margin_t=150)

time.sleep(2)

fig.write_image('exp-images/start_absvsgrowth_data.png', format="png", width=1400, height=1000, scale=4)

fig.show()

Displays in my notebook:

But not in the export
