There is a export function which allows you to save images without the need to connect to plotly servers. You can find it in the plotly package doc:

p <- plot_ly(...)
export(p, file = "image.png")

You can also save the image in html file which allows you the plotly experience like zooming or showing annotations by using htmlwidgets::saveWidget:

p <- plot_ly(...)
htmlwidgets::saveWidget(p, file = "image.html")
