Hello! On a wikia, I've introduce an easy way to suggest a resize option for pictures, called INLINE. The idea is to give opportunity to others contributor, who pass after me on the same page to resize, every picture by an amount, in only one click. Per example when you don't know if the size suggestion you give for pictures inside a list of items would be critiqued, it may be better giving other's opportunity to easily modifies your work. There is an example on a page : http://therunefactory.wikia.com/wiki/Cooking_and_Recipes_(RF4)

Problem occur when I want to re-use this idea on an another wikia who doesn't have the required extension installed.

Question is, : How could I declare a variable, as inside the body element of an HTML page, that I could reuse later on a page without or the parser function extension?

Per example, could someone help me correct this code plz?
 * 1) Hello world
 * 2)
 * 3)

I would like to make this variable declaration work on this page : http://fferpg.wikia.com/wiki/List_of_Items.

I was thinking about using a template, by I hope there is other's option too.
