Go to
http://www.photobucket.com/ and create an account. (free)
When you have an account, press 'add image' or some equivalent.
It will ask for a URL or whatever of that image, but if it is saved onto
your computer, click "BROWSE".
This will take you into your pictures. If it is in 'My Documents' or 'Desktop'
or on a disc, press the dropdown thing that says "Look in" My Documents.
click the image and press, 'open'.
That will save it in your photobucket account 'album'.
You will see the URL label there somewhere, so copy that to a post.
now while it is in your post, highlight the URL and push the URL button.
now press
PREVIEW to see if it works because it is very annoying to
have dead links in a post.
Highlighting can be used also, with the other buttons, too ie:
bold, italic, underline, etc.
