If you are newly registered as a forum user, you can add a profile picture easily.
Once you have logged in, look in the top right hand corner of the web page. You should see your name. If you hover your mouse pointer over your name, a sub-menu will show. So now hover over the word ‘PROFILE’ and you will see another menu showing ‘Change Profile Photo’ (see picture)
In the next screen,use the button ‘Select you File’ to add your own image. Good Luck..!!
