I'm not sure if this is a generic problem, but see:

The following image's text doesn't scale with the image:

The image link in the article is:

proportions.svg|right|200px|thumb|Proportions of uranium-238 (blue)
and uranium-235 (red) found naturally versus grades that are enriched
by separating the two isotopes atom-by-atom using various methods that

I've checked on Firefox 3.0.3 and IE 7.0
I believe that this must be a recent change - I check that article
semi-regularly (it's on my watchlist along with other nuclear topics)
and I don't recall seeing any problems with it...
