If that is the case, can I override this somehow so that the images not appear as broken?
you can fix this in the forum content by referring to an image resource on your server rather than referring to an unreliable image server.
If that's not the case, can I add some sort of code to my .htaccess file to prevent this image breaking from occuring?
as it is, your visitor's browser is not making this request from your server, so your .htaccess file cannot do anything about how that browser renders that img element.
