Image rollovers by naming image produces error in html validator

How do make a standard image rollover compliant to w3c 4.01 transitional.

This is what the validator says..

<!-- snip


Line 37, column 200:
  ... ,'icon01of')"><img src="gui/la_ws_nav01.gif" name="icon01" width="103"
...
                                                        ^
Error: there is no attribute "NAME"


Snip -->

Thanks
