Images with a width containing a decimal dot are parsed incorrectly, width the dot being disregarded (so that [[Image:Foo|3.25px]] will be 325 pixel wide). See for example: http://hu.wikipedia.org/w/index.php?title=User_vita:Tgr&diff=prev&oldid=3050910 Using fractions in image sizes does not make much sense, nevertheless it is used by a number of people (especially in signatures), and when a lot of images suddenly increase by one or two orders of magnitude, the result is not pretty. (Note also that CSS does allow for such sizes: http://www.w3.org/TR/REC-CSS2/syndata.html#value-def-length )
Correction: it does not only disregard the decimal dot, but the whole width parameter. The image appears at its original size.
Well, that'd be because it's invalid input -- now that we have improved the input validation, it's rejected. We could perhaps allow them; they'd still get rounded off of course.
