Byrne Reese has released MediaManager beta4... an updated, overhauled, "new and improved" MT32-friendly replacement for BookQueueToo, as well as MTAmazon32v1.0 (repackaged and updated MTAmazon). Very cool! Check out the screenshots for a walk-through and you'll be impressed, too.
Installation (on MT32b2) was not too difficult. First, I edited mt-config.cgi to specify my mt-static path (even though I do have it in the default location). Then I uploaded MTAmazon32.pl and MediaManager into my plugins directory (making sure to CHMOD 755 mmanager.cgi). In System Overview/Plugins I configured MTAmazon32 with my Amazon subscriber ID and cache location. Then I configured MTAmazon32's Amazon associate ID through each blog's plugin settings.
Oh, I forgot about MediaManager's static folder. Rename it mmanager and move it to your mt-static directory.
I think that did it. Hope I didn't forget anything... oh yeah, the cache folder... I actually forgot to create one and there's been no fussing about it. Is it not required with MTAmazon32? (I have gone ahead and created it.)
Anyway, the awesome new "Review" feature looks... well.. awesome!! Byrne brilliantly incorporated the Amazon image hacks that he had described previously on his site. I finally figured out how to use it. After you create your review (I had to do it as a draft), go to your entries and edit it by selecting a new Text Formatting option: "MediaManager: Layout1", select Publish, then save. You will have a very cool and nicely formatted review entry. Unfortunately, this plugin does not (yet!) have a php counterpart, so the review entries will not work with dynamic archives. :-(
FYI, MediaManager beta4 results are in the "books" section on my beta blog as well as in the left sidebar on this blog.
