Yes, when you upload a picture to HEF, it goes onto our server, and that's where it takes up space. When somebody clicks on that thread, the image comes from HEF's server, the same as the text does. I just did some poking around, and I can't find anywhere that tells me how much space any given user is allowed to take up, but statistically, the top posters of attachments literally have several thousand that they've uploaded. Don't worry about being a hoarder. The space you're taking up is in our attic, not yours.
