Like Boingo said, you'll need to use a service like PhotoBucket or ImageShack. You upload a picture from your hard drive, they host it for you for free, and you get some HTML code that you can paste into your profile here at Tron-Sector.
For the Member Upload feature, it's basically the same idea. You upload a picture or file from your hard drive, and eventually it gets hosted here. But the difference is that someone at Tron-Sector has to approve your upload first, before it shows up.
Problem is, right now the Image Gallery on Tron-Sector is busted. It hasn't been working properly since the downtime the site had a couple of weeks ago. It still needs to be fixed. Member Upload isn't working either, right now.
