Add an i to the end of the statement:

s/h\.(.*?)\.JPG/$1.h.JPG/gi;

However, this will match files that start with a lowercase h as well as an
uppercase H. If that's fine, then this regex will do the job.
No... the problem is that it will take

h.foo1.jpg
and replace it with
foo1.h.JPG
Which probably won't work (since the case of the extension changes and most *nix are case sensitive...) The regex should be

s/h\.(.*?)\.(JPG|jpg)/$1.h.$2/g;

Or even more generally:

s/h\.(.*?)\.([Jj][Pp][Gg])/$1.h.$2/g;

Which you can wrap up in a single command like so

perl -pi.orig -e 's/h.(.*?).([Jj][Pp][Gg])/$1.h.$2/g;' *.html

which will do the replacement on all HTML files.. saving the originals with the extension .orig in case something goes horribly wrong and your need to "undo" it.
