Ah, ok I figured it out. It looks like flickr changed something when you copy the [img] tags from a picture. There is a [url] tag right before the [img] tag that you have to remove manually before you post. If you don't remove it, the VB software assumes the whole thing is a URL and attempts to posts a link.
This must be something new to Flickr as I use to just grab the entire [img] link without having to remove anything.
At any rate, I'll be putting on a couple of fatties today to try it out and burn off any manufacturing residue before I try the butt next Saturday.
