Dear Pablo

The short answer to your question is that your filename is "hard-coded"
into the recorded commands, and therefore the code will not work on an
image with a different name.
So you need to do something like:
imageName = getTitle(); // assumes the image you want to process is
selected (active)
and then use imageName in place of the hard coded names.

However, what you really need to do is check out:
Macro Programming in ImageJ
http://wiki.cmci.info/documents/ijcourses

and particularly page 76, which will tell you how to read a list of
files and process them.

It will involve some learning curve on your part, but it will pay off.

God luck
