works with NS3 thru NS4.5 IE too
does not work with NS4.5, but it should methinks ha! it does work with NS3, but crashes at reload IE does it!
NS3 - NS4.5: onError is triggered for broken lowsrc, too, and no SRC is loaded to fix it, even if the SRC is fine. IE: onError is NOT triggered, SRC is loaded instead.
NS4.5/Unix: If src is broken, but a valid lowsrc is given, onError is not triggered - and no picture is shown! Bug! NS3: onError is triggered IE: onError is triggered, and no picture is shown! Wrong, too!
