Oh jeepers, please don't do this to me.  Yet *another* interpretation
for double brackets?  

"Well, double brackets are used to be able to specify alternate 
text for a link, except when they begin with 'image', in which case 
they're an alternate syntax for image URLs to let you specify alt= 
text, and you can't specify alt= text if the image is being used as 
the text of a link, because PmWiki doesn't support the  [[WikiWord 
[[image http://foo.com/cgi-bin/mapper.cgi?parm1 alt=My_Map]]]] markup, 
not that anyone can figure out what it's supposed to be anyway, and
if using the brackets you have to figure out yourself if you want 
align=left or align=right added to float the image because PmWiki 
can't add it for you...  sigh."

We might as well just write <img src='....' alt='...' />.

The spaces are somewhat complicated but not *that* complicated.
