Just a minor question about using this: I want to use this in a data template that checks for the existence of a file from the Wiki's file gallery based on { {PAGENAME}}, and the usual, ideal case is that it would exist, and display a corresponding image for the article on the page. The documentation to which you referred talks about it being an 'expensive' function, does this mean that I should rethink using it in this way?
