Add some icons (flags) on a website for multi-language support

*I have a website:* *<[login to view URL]>* *This website has the home webpage where somebody can select a category.* *After selecting the category, the visitor is redirected to the main webpage where he can see all the categories on the left and go through them. An example is this:* *<[login to view URL]>* *The main website is made on Joomla.* *That means that we have two different part of the website, the homepage and the main website.* *What I need is to add 5-6 flags on top right corner of both of them, giving the option to the visitor to see the website in different language.* *I have the flags, I have the websites translated in different languages and they are online and working.* *So, I need somebody to add the icons and make the proper redirects (URL). For example, in this way, when somebody will read the website in Greek, by clicking on the French Flag, he should be redirected to the French Version.* *So I need somebody to put the Flags with the proper URLs.*
