Umm, how does this not work?  The above example displays the word 
"blurring" that is linked to the given url--i.e., exactly what I would
expect.  Permuting the arguments doesn't make a difference here--or
am I misreading something?

PmWiki only generates an image when the *text* to be displayed (not the
target) is both a URL and ends in .jpg, .gif, or .png.

You're probably worrying about the case

  [[ImageBlurring http://uri.org/effects.php?src=rose.jpg&arg=blur]]

which doesn't produce an image, but (I think) it's fairly easy to
detect what is happening and fix it (i.e., "the url has to end in
.jpg to be treated as an image).  And so far I still prefer 
"swap the arguments" to the alternative:

  [[ImageBlurring [[image src=http://uri.org/effects.php?src=rose.jpg&arg=blur alt='alt text']]]]
