Is it possible to pass as argument to a template another template? For example I need to store in a template the url of a image and then pass this template to another template. So when I change the image url inside the first template automatically I change the image in all the other templates.

I'm not exactly which case you are asking about but you can do any of the following and there may be other possibilities (there are also other examples at MetaWikiPedia:Help:Template):

case 1.

article = "blah", wikitext = "{{blah1}}" template = "blah1", wikitext = "blah {{blah2}}" template = "blah2", wikitext = "blah blah"

article blah displays text: "blah blah blah"

case 2.

article = "blah", wikitext = "{{blah1|blah2}} template = "blah1", wikitext = "blah {{{{{1}}}}} template = "blah2", wikitext = "blah blah"

article blah displays text: "blah blah blah"

case 3.

article = "blah", wikitext = "blah {{blah1|blah|blah2}}" template = "blah1", wikitext = "{{{1}}} {{{{{2}}}|{{{1}}}}}" template = "blah2", wikitext = "{{{1}}}"

article blah displays text: "blah blah blah"

I'm not sure how deep you can nest templates but it seems you can go at least 3-4 deep.
