When Tidy (at least the January version, I did not yet get to test the new April version) is called with [--alt-text ''] (or with the line _alt-text: ""_ in the config file), your example <IMG SRC="fred.gif"> is tidied as: <IMG ALT="" SRC="fred.gif"> Running Tidy (Jan 13, 2000) again on this result, you will get: <IMG ALT="SRC=fred.gif"> Tidy chokes on its own empty attributes - interestingly it has no problem with empty ALT values, if the ALT apears as the last attribute of the IMG tag, right before the concluding ">". I am going to try the new April version today, to see whether this bug got fixed... sebastian At 19:46 01.05.2000 -0400, J.
