I had thought this method. The problem is there are more than one attributes of the
custom tag. How it knows which one the value is for the attribute "src"? When I try
this way, I get an error as:
According to TLD, tag mm:imagesizer must be empty, but is not
I think it complain no value for the required attribute "src".

When I use this method, the translated value in the output html file is <img
src="${photopath}" alt="Photo">.
Any thought?
Thanks,
