Hey KTO,
To insert any image with a URL or web address into a post, just put the URL of the image in-between "IMG" tags. Don't put the whole HTML code, but just whatever is after the "img src=". This is the URL of the image.
Below is what you would enter into your post (I didn't put the correct brackets around the IMG tags so you can see it here):
{img}http://smileys.smileycentral.com/cat/7/7_3_101v.gif{/img}
And here it is with the correct brackets... it appears:
Hope that helps.
