ok, I have no idea what tttwt means, but I'm assuming it didn't work. I think I see why.... It was my mistake, I thought if you cut paste that IMG tag, it would work fine.., and that is not the case.
Here's exactly how to do it, assuming you're using photobucket.
Open your photobucket account, and upload the pic. Under the pic, right click and copy the URL line..
In the buttons above the post post window, click the "IMG" tab, and paste the URL in there.
After its pasted, it will look similar to this. I didn't include the first and last brackets, so you could see it.
Like I said, the [ at the beginning is gone, and the ] at the end is gone, if I had those characters.. This is what I'd get...
Hope that helps...
