I'm part of a photography forum that is considering switching from Xenforo to WPForo.  We've set up a test forum using WPForo and have run into an issue with image linking.  Most of our members have their own sites and prefer to link images from their sites rather than upload.  We prefer that to as it saves server space.  Our members are used to the BBCode functionality in Xenforo which we understand is not included in WPForo.   Many of our members use either Flickr or Smugmug for their hosting and we're running into issues with the images linking correctly and were curious what we need to do to make this work correctly.  Below are the HTML codes straight out of the share functions from Smugmug and Flickr:
