Now what's happening....!

Changed my profile picture last night, or at least thought I had. (Do this occasionally as only way quickly to change photos on here) But... despite sleeping on this and expecting my new profile piccy to have loaded (5 mins is stated), lo and behold when I post, my original photo of dogs on beach comes up, but in my profile it is a cake! I had thought my limited IT skills were the main problem using this site, but deep down clearly it isn't!

Baffled? probably at the touch of a particular button this will be resolved, but there are an awful lot of buttons to go at!
