Flags in header

[Vlk1]

Hi, I'm here again with a big request. I would like to have only one selection in my header, specifically "Czech" and "English." I want it to look like this: the Czech Republic flag followed by the currency (CZK), and below that, the EU flag followed by EUR. Clicking on the EU option should automatically switch the e-shop to English. Is it possible to set this up, please?

It seems like it automatically translates to ones language itself.

I have add this code but the picture appears only for EU, not CZ, idk why.
