 * I just updated Imsanity to 2.17 which should fix that issue on wordpress installations
   prior to wordpress 3.0. If you download and install that the multisite check 
   shouldn’t occur.
 * It was a simple fix, but you should probably upgrade your install. I’m pretty
   sure the old versions of WordPress have security issues.

 * Many thanks, Jason. appears to be working! Note that search images results window
   is only 50px high, with no scroll bars or window resize option, but files can
   be viewed one at a time anyway by clicking in the window and using up or down
   arrows to scroll through.

 * Hmm, interesting. what browser & version? the style is baked into the html at
   250px heigh w/ scrollbars, so that’s kinda weird.
