Amanda (fored) probably has one of the most (if not the most) sensible replies so far...
Addressing AverRal's 2nd post (the 3rd version of it - I think it was edited twice before...? Not sure what the other 2 versions were like...):
With consumerism [sic] of goods and services to cater to every of our human need possible, comes with the packaged human product for people to worship and admire... for the talents they appear to possess no matter how superfical it might be.
I personally wouldn't want to be worshipped, heh. But yes, AverRal's general idea is valid to some extent IMO; basically you can't avoid having an image.
It depends on what image you project, and how consciously you shape it (or don't try to shape it), etc. But the bottomline is that you will always have an image.
George Orwell echoes the same idea (although he addresses the issue of writing, and the writer's aim/intention etc) in his essay "Why I Write" - the idea that whether you like it or not, whether you're conscious of it or not, you are putting forth a message to your audience. Example: Even if you're "just", for example, a down-to-earth home-studio singer-songwriter acoustic guitarist that records tunes in his/her room and puts them up on MySpace - that automatically places you in a category, in a genre, which by default forms part of your image (think of the keywords I've just used: singer-songwriter, acoustic guitarist, home-studio, MySpace...)
However, it's not just about having "attractive" physical features. It's not just about having "a face to every [sic] music". It's about having a well-developed, three-dimensional image, which does not equate a mere pretty face. It's about pitching a story, a concept, a narrative at people, that is encapsulated in those visuals: not just the artist's face, but the artist's style of dress, the artist's surroundings that he/she is photographed against, the artist's habits/hobbies, the artist's background (i.e. his/her "life story")... etc.
It's not merely a face; the face becomes a symbol of all of those narratives that (whether subconsciously or consciously) are fed to you.
There are many, many attractive wannabes sending their demos out to record labels - some of them have actual talent, some less so... but IMO what really makes or breaks an artist's appeal is their ability to cultivate a three-dimensional image. Sometimes (or most times) their management and label comes up with the image, but the artist has to be able to pull it off. (This is probably very closely related to the "X-factor" issue, come to think of it.)
In that sense, posting up pictures (in itself) isn't enough. For 'girl-power' solidarity, it could be a fun thing. But if it's posting up pictures for more than just female-musician-solidarity; if it's posting up pictures more related to the "intellectual" reasons that AverRal cited... er... then the pictures themselves should strive towards more inventive standards I guess. But if it's just for fun then anything goes what (as long as it doesn't violate any of the msgboard rules here) - if you don't like looking at the pictures, then don't look.
Sorry if I've over-intellectualised. On some level, yar I guess this could just be a fun thing (like a "let's post up our photos for fun!" kinda thing... like you see on lots of blogs these days...) but every time this sort of stuff comes up I tend to think of all the other dynamics, assumptions, mentalities etc that are working beneath the surface... er, especially if it has something to do with females and/or music. (yar, and this thread happened to involve both, heh.)
