Uh, I don't see any images in that post...
The [IMG] tag is part of the UBB code stuff (like doing a [b] instead of a < b>). Most forums don't allow HTML (no trust in the world!), so the software is expecting the UBB codes. And if it finds HTML that corresponds to UBB, it always converts it, as it did in this case.
