Ted,
It looks like you pasted the link directly into the forum posting window, rather than pasting through the "Enter an Image" function.
Step 1 -- Click on the "Enter an Image button in the posting window:
Step 2 -- Paste the link into the window that opens up.
By the way -- absolutely beautiful pond!
Ken
EDIT: I see Theo posted at the same time I did. The function I mention above adds the [IMG] and [/IMG] that Theo mentioned.
