Hi,

We are trying to show the number of files in a Commons category[1] at a page in meta[2],  but we are not sure how to make interwiki calls as most browsers block it.

* [1] - http://commons.wikimedia.org/wiki/Template:India_loves_Wikipedia_event
* [2] - http://meta.wikimedia.org/wiki/WikiConference_India_2011/Wiki_Outreach#India_Loves_Wikipedia

Any lead in this direction will be appreciated. 

Thanks,
Sreejith K.
