That will match
$1: From the first ">" to the ">" in the img tag in line 7.
$2: "Computer" in line 7
$3: From the newline after "Computer" to the opening "<" in
"</html".
In other words it will only replace the last "Computer" in the file.
The "g" is ineffective, since there can be only one last "computer".
The "m" doesn't seem to have any effect either.

This will replace any "computer" after a ">" and before a "<" on the
same line. In the example file there is only one "computer" left which
matches that criterion, but that doesn't seem guaranteed.
