Frog or Toad

I know we have a large toad in our garden. It's brown and warty looking. 

However this fellow shown below has me confused. Is he a young toad or a frog ? I see this guy quite frequently. He lives at the bottom of our garden . I can get quite close to him /her to take a photo if I quietly sneak up.

Okay what is it ? Frog or toad ? Post in the comment section.
