The "&"-sign followed by various unknown terms

That's it! Forget it!
I'm not going to change it anymore. It's not clear to me what happens, but it seems that unusual signs (written on Picasa as commentary below pictures) convert into "&xxx".
The "xxx" stands for 'quot' or 'amp' or something else.

With unusual signs I mean: "&", " " ",...

I just wanted to let you know amigos.
