c.f. w:c:psiepsilon:AdS_CFT, I want to change the default "External Text" Icon which appears for arxiv preprints. The default one looks like this:

I want to replace this with the image for arxiv preprints on wikipedia, which looks like the Adobe PDF icon.

I suppose this can be done with CSS, like: .external .text { background-image:url('THIS-IS-THE-URL'); }

But I'm not sure if that would work, and I don't want to cause some mass-disruption, so  I just wanted to verify whether the above code is correct ? .

P.S. I think this image is usually changed using the installed MediaWiki files, but obviously only Wikia has these, which is why I'm unsure as to whether the above code would work.
