Finally found help how to attach picture and other attachments from textra.
Like others have said "The only way I can use the + sign is to physically turn my phone sideways first. Otherwise the + sign is inactive."
The problem was with my android phone settings.
Go to main settings > Display > Home touch buttons > Hide Home touch buttons : find Textra in the list and set to OFF. Some of the menu names may be a little different but it wasn't difficult to find once I knew what to look for. Now when you hit the + sign the proper attachment buttons should appear.
