Plugin is really good and adds much flexibility to the site. An upload from the front end can really make a site much more interactive plus the ajax process viewer helps a lot. And in the end when images are uploaded, you get to view the uploaded images too. :)
I hope this is not the end and wish this plugin gets bigger and better in days to come.
One small mistake:
The plugin shortcode is [AAIU] but in plugin description field its [WAIU] . You should fix that ASAP else it will create confusion.
