& should get translated to &, but not vice versa

I have a page with thumbnail pictures that can be clicked on to see a larger

<a HREF="show_pic.php?pic=blah&caption=Some+Text">
I access the 'pic' & 'caption' attributes with $_GET['pic'], etc. Pretty
standard stuff.
I have PHP set up so that error messages get mailed to a specified mail
account. Every so often I get the following error message:
Undefined index: caption
In file /home/..../show_pic.php, line 64
page: /show_pic.php?pic=gb3.jpg&caption=Some+Text
The problem is obviously (I think) that the $_GET['caption'] is failing.
What I can't figure out is why the '&' got turned into '&'. Is a
browser doing this?
