Embed image in Plotly

Question

I am trying to embed image in Plotly graph but somehow the image is not displayed. Does anyone have any idea what am I missing:

library(plotly)
p <- plot_ly(x=c(1, 2, 3), y=c(1, 2, 3), type='scatter')
p2 <-
p %>%
layout(images = list(
list(source = "https://images.plot.ly/language-icons/api-home/python-logo.png",
     xref = "paper",
     yref = "paper",
     x= 0,
     y= 1,
     sizex = 0.2,
     sizey = 0.2,
     opacity = 0.8)
)
)
p2

Answer 1

may be problem in 'source'-

Specifies the URL of the image to be used. The URL must be accessible from the domain where the plot code is run, and can be either relative or absolute.

And second list you don't need.

layout(images =
  list(source = "https://images.plot.ly/language-icons/api-home/python-logo.png"...
