John, this is how Scott has described the process in an earlier thread:
-Find a picture on the internet.
-Right click on the picture, which will bring up a Windows dialog box and then left click on properties.
-There should be a small window containing several information boxes, one of which will show the web address of the picture. Use your mouse to highlight/color this address, right click again to bring up another dialog box and then left click on copy.
-Go back to your post and right click to bring up a dialog box and left click on paste, in order to paste the message into the body of your post.
-Now color/highlight the web address that you have just pasted into your post, and left click on the image icon (located just above and to the right of the winking smiley icon). You will now notice IMG surrounding the web address.
-If done properly, the picture will show up in your message preview.
Hope this helps!
