OK, so my current picture is all me, bad hair and everything

.
A while ago I got sick of seeing my awful-looking hair staring back at me every time I posted here, and was using a picture of Shirley Manson (singer from the band Garbage) as my avatar. Mainly because I didnt have access to a camera to take a better picture of myself, I think she looks pretty, and I really like her music. So I went with it.
And the thing is, people did start to assume that she was me, simply because I had her as my avatar. Never did I even try and allude to the idea that it was me, or I looked anything like her - people just assumed anyway. I figuired she was famous enough that people would just realise - and they didn't. Does this mean that I was being dishonest simply because others were assuming a picture on my profile wasn't a picture of me, even though I thought it would be obvious to most that it wasn't and I made no attempt to represent her picture as being myself? I don't think so. Assumptions by others dont equal lies on my part.
I've been meaning to borrow a camera off one of my friends to get a better picture of myself for the forum - decent hair, make-up, looking like the attractive and confidant woman that I sure as hell know myself to be. I'm back to my old picture for the moment until I can - what it comes down to is I really don't mind people seeing what I look like, I'd probably post a lot more pictures if I had the means to actually take them. I'm proud of the way I look and I really don't care who sees me, bad hair or not

If I did look like Shirley Manson I can't say I would be complaining though
