For *BORDER* tags, you're in luck:
/<img(\s+[^bB]\w+=("[^"]"|\S*))*>/i
But that is on the (valid?) presumption that the ONLY attribute for an <img> tag
that starts with the letter "B" is "BORDER". I suppose I could be wrong what
with all the custom attributes that MSIE has, etc. But if there ARE other
attributes that start with B, then the above DOESN'T work, since it'll ignore
anything that's got an attribute that starts with B.
