In ggtree you can add images to tips as such:

 library(ape)
 tree <- read.nexus("https://raw.githubusercontent.com/rgriff23/Dissertation/master/Chapter_2/data/tree.nex")
 phylopic_info <- data.frame(node = c(124, 113, 110, 96, 89, 70),
                             phylopic = c("7fb9bea8-e758-4986-afb2-95a2c3bf983d",
                                         "bac25f49-97a4-4aec-beb6-f542158ebd23",
                                         "f598fb39-facf-43ea-a576-1861304b2fe4",
                                         "aceb287d-84cf-46f1-868c-4797c4ac54a8",
                                         "0174801d-15a6-4668-bfe0-4c421fbe51e8",
                                         "72f2f854-f3cd-4666-887c-35d5c256ab0f"),
                             species = c("galagoids", "lemurs", "tarsiers",
                                         "cebids", "hominoids", "cercopithecoids"))
 pg <- ggtree(tree)
 pg %<+% phylopic_info + geom_nodelab(aes(image=phylopic), geom="phylopic", alpha=.5, color='steelblue')

 d <- data.frame(node = c("70","89","96","110","113","124"),
                 images = c("https://i.imgur.com/8VA9cYw.png",
                             "https://i.imgur.com/XYM1T2x.png",
                             "https://i.imgur.com/EQs5ZZe.png",
                             "https://i.imgur.com/2xin0UK.png",
                             "https://i.imgur.com/hbftayl.png",
                             "https://i.imgur.com/3wDHW8n.png"))
 pg %<+% d + geom_nodelab(aes(image=images), geom="image")

However, is there anyone who has gotten it to work with collapsed clades using:

tree+collapse(node=nodeid)+geom_cladelabel(node=nodeid, "New clade", align=TRUE)

for example? I know there is a geom image in geom_cladelabel but can that be used? If so, how?
