I'm curious what the reason for the last .* is. You want to replace
everything up to the end of the line?
Also, once it's matched either a single or double quote, best to stick with
it offcourse, so alt='15" monitor' works:

'/<img #opening tag
[^>]*? #random chars within tag up until next match
(alt\s*=\s* #start of alt attribute
(\'|") #get the quote
([^\2]*) #everything except the used quote
\2) #endquote, end of alt-attribute
[^>]* #allow for excess chars within the tag (why even
match them?)

Grtz,
