[Mediawiki-l] Embedding a default template on each image description page

[Wikimini]

Hi,
I need to embed the same template on each image description page (the page
you get when you click on a thumbnail image).

I found a similar request here:

According to answer given by Brianna (
http://www.gossamer-threads.com/lists/wiki/mediawiki/129448?do=post_view_flat#129448),
javascript seems to be the easiest solution to insert default text in
summary box.

Since *I don't speak javascript*, I thought it best to ask here. Thanks in
advance for any help.
