[Plugin: NextGEN Gallery] Need to add a second textfield in the manage section of the dashboard

Hi,

i am trying to make a multilanguage site.
One problem i am encountering is the description text.
Now there is only one textfield for description but i need two.
So that you can type one language in the first and the second language in the second textfield. If the textfield then automatically also sends the text in between these tags <span lang="en"> </span> for the english text and <span lang="nl"></span> for the other text than my problem is solved because of an other plugin im using.

i hope you can understand what i am trying to ask :s..
