Not a problem, the lanc is showing now
On flickr under your image on the right side of the page select the curved arrow between the star and the downward pointing arrow.
Select BB code, in the box that comes up select the bottom window and select a size you want, then right click and copy the blue code above that window.
On here if you paste it into the reply box it will link as your Lanc is to the page on flickr, but if you select go advanced tab below the quick reply box and post the image in there and untick the three miscellaneous options boxes it will post the image like mine has.
For some reason the site now has them on as default..
