I got tipped about postimage.org for off-site picture hosting - you can choose the size you want your picture to be and whether you want the link to expire within a set amount of days or never. No registering needed, just click upload. This seems very similar to tinypic to me, so I'm a bit sceptical. Tinypic reuses links sometimes, so after awhile your picture disappears and/or gets replaced by some other user's picture. Postimage does have the option of "no expiration", but it seems too good to be true, I guess. It's all free, how can they afford to host all these pictures without ever freeing up space? Does anyone know if the picture stays uploaded, with the same URL, "forever"?
