Surname in photo gallery

My account was opened when I joined the 'Garden for Wildlife' section and when I first looked at the community pages I saw that my screen name was my surname.  I presume that this was by default as I would not have set it up this way.  I changed my screen nickname to Sarum Bat and updated my profile which worked fine but when I had a go at uploading some photos recently I was surprised to see that they were shown as having been uploaded by my surname.  Does anyone know if I am able to amend this please?  Perhaps I am missing something or doing something wrong.   I would be grateful for any help.

I am enjoying the wildlife questions and looking at the bird photos.  Keep up the good work.

 

There is something new to learn everyday...
