Posting an image... Images must be hosted at a location on the internet. (Suggested site: imgur.com or flickr.com)
Check the image below. Right click on the image to see the copy image address popup option:
Image URL ends in .jpg or .png or similar.
Navigate to your image page. Right click the image and copy the "propeties". This must be an image address (url) rather than a url to a page. Click the above image to test and look at properties and address (url).
Rather than a link to the page it was on. The address should end in something like .jpg or .gif
Use the buttons above the post text area to find the proper code.
Use [img]then%20the%20image%20url%20and%20click[/img] again.
Be sure to have the option " Disable BBCode " unclicked!
and you are done.
