Ok, you post a photo and that is certain size (42KB).
A lot of sites have a bandwidth limit each month and if it exceeds it the site is shut down for the remainder of the month. And the guy who runs this is on a paid server anyway, domain name and webhost show this.
People really have no clue about this issue, and it's to ok post a pic off yahoo or sport.com, they have no problems in this respect but someone's personal site is another matter, if I find somebody does this with any pics from my site then I ask them to remove them or e-mail the webhost to get them removed. I don't mind if they host them on their own server.
It is a matter of respect.
