Change flag for translation

Lets say we want to change translation flag which shows in GUI top right corner.

For example let's change green Arabic flag to Egyptian flag.

First of all go to /home/mor/public/images/flags and find Egyptian flag image. It is egy.jpg

Now go to database table [translations] and find row with Arabian translation.

Update it's field flag with value 'egy'.

Relogin to your MOR GUI and flag is changed.
