PHP arguments as an obstacle to validation

Hello!
(Sorry for the last truncated one)
 
I noticed something peculiar with the W3C validator: It thinks a link which
contains a URL to a PHP script with arguments is invalid even though it is
in double quotes.
This link: <a href="image.php?sizex=358&sizey=292&alias=megpic1"> gives
a.. Line 10, column 33:

                                   ^
Error: unknown entity "sizey" 

a.. Line 10, column 35: 
  ... ref="image.php?sizex=358&sizey=292&alias=megpic1"><img src=" ...
                                         ^
Error: unknown entity "alias"

What might be wrong?
