Conversion not implemented for geom_custom_ann (basic geom_custom_ann)

Tried to use ggplotly with a custom raster background from ggplot:

library(ggplot2)
library(grid)
library(png)
df<-data.frame(x=1,y=1)
Art <-readPNG("Artemis_Picture.png")
a<-ggplot(df, aes(x,y))+annotation_custom(rasterGrob(Art))+ geom_point(color="red", size=6)+ theme(axis.line=element_blank(),axis.text.x=element_blank(),axis.text.y=element_blank(),axis.ticks=element_blank(), axis.title.x=element_blank(),axis.title.y=element_blank(),legend.position="none", panel.background=element_blank(),panel.border=element_blank(),panel.grid.major=element_blank(), panel.grid.minor=element_blank(),plot.background=element_blank())

We'll keep a list of unsupported geoms in #348. It's not very clear how to translate this geom, so it's not likely to happen soon.
