Inserting an image as a link into a header

Hi,
I am using RW 8.7 with Stacks and with the Flood theme.
I would like to insert a small picture of a flag into the header and use it as a link to a different language version of the site.
I am not familiar with Extra Content Snippets, if that is the answer…
What would be the simplest way to insert the flag with the link on top of the Menu content ?
Thanks for your help.

@willwood the maker of ThemeFlood also has a product called RWML (RapidWeaver multiple languages) that might be better then the flag thing.

He also has some good knowledge base articles on using extra content

Great ! Thanks Teefers, I’ll explore that.
