Hey there Malenurse.
First you must have your pictures posted on the net on a picture hosting site like hunting-pictures.com or msn. Once you have your pics uploaded to the site then go to your pics and right click on them, go to "properties" and copy the address (URL). Start a post and click on the "Insert Image" icon and it will insert the command needed in brackets. Paste your address in between the two bracketed commands and your picture should appear. Do the preview until it works.
I've had problems with doing it from Webshots so as you've seen before I just paste a link to my albums and tell them where to go. Like:

Good luck and can't wait to see that 3 pointer of yours.
