Ok!
A photo posting lesson in simple stages:
1 go to photobucket.com or some other photo sharing site. Flickr is another.
2 once you have set up an account, upload the photos using their "upload" button, which will enable you to click on pics from your computer.
3 those pics are then held by servers at the photo site.
4 once they're uploaded, you can share them here by pointing your cursor at the picture on the site, which opens a menu like this like this:
http://i150.photobucket.com/albums/s...theist/111.jpg
5 left click on "IMG Code" to highlight, then right click to copy.
6 paste exactly that in your post as I did above and the pic will sit there for you.
