Help!!

I hope some of you experienced bloggers can help me! I have a profile photo which sometimes shows up when I leave a comment on a post. But - when I join someone's blog as a follower I just get that anonymous silhouette that goes on at the end of your list of followers. I follow lots of blogs but I don't actually have many followers. Now that may be (and probably is) because my blog is a bit boring and people don't want to follow it!! Or it may be because the people I am following don't know I am following them. It's probably the first reason but I would still like to have a follower piccie even a symbol would be better than nothing. I'm sure I'm missing something but blogger help is absolutely no help. It can only tell me how to add a photo to my profile or how to upload photos. Even I know how to do those two things lol. So I'd really appreciate it if someone could point me in the right direction please. Thanks in anticipation of help. I know crafty bloggers are a helpful bunch.
