First, you have to post them to your web space provided by your ISP. Go to your ISP's support pages if you need directions.
Whatever you do, [b]don't[/b] use a free web hosting service like Geocities because they don't allow remote calls and while the images will show up for you and you only, no one else here will see them.
Once you uploaded your pics and figured out the URL, all you have to do is put "image tags" around it -
at the front and behind it. (Note: use the "[" and "]" instead of the "<" and ">" in the example. I had to do this so the text would show up on this page.) For instance, if the picture is at http://www.myisp.com/~myaccount/picture.jpg then the command should look like this:
http://www.myisp.com/~myaccount/picture.jpg
One last thing - be sure to format your images to less than 1000 pixels horizontally (less than 800 is better) so we don't have any giant, slow loading pics that no one can see anyway.
