DC hub is the best source. I almost hate to tell you about this site but there is a fan from Finland who has taken a bunch of great pictures over the years. He has some expensive cameras and he's managed to sneak them into events we're they're not allowed. Like I say, they're great pictures, but he insists on putting his monogram on them. They're mostly from shows but he has them filed by year so it might give you a general idea of what your looking for. I believe his site is safe.
After she quit or what ever you want to call it in early 2004, she sort of disappeared for a couple of years until she started working on her next album, so I don't think you'll find many pictures from that time frame.
If you have problems with the hub, we sometimes share things through Google drive too, but if you're looking for a lot of her videos, you're best off going through the hub.

Here's also a link to a thread in our forum where a poll was taken asking members what their favorite hairstyle was, but it only listed 12 and this was back in 2012, so there's been a few added since then.
