5thElefant, good tip.
I was going to say, scroll down & select “Flickr.com”, but your method is much quicker.
For info, posting this from an iPhone, but basically do as 5thElefant says but after pasting the url in to a browser window, the little sweeping arrow button opens a box with a code, with an “Embed” option. To copy it, hold on the code till some of the code is selected, then select the left dot & sweep to the left to the start, & select the right dot & sweep down to grab the code to the right that isn’t shown, then the copy option comes up.
It doesn’t say the code is a bb code but pasting it under here gives…
