Well, my previous review is needed to be changed.
I've found out that the /wp-content/uploads/ in the FTP will be filled with a lot of different sizes of pics(thumbnails), month by month, year by year, which are auto generated by this plug-in......I DON'T LIKE IT AT ALL.
But, if you don't care about it, this plug-in is actually looking good...
>>It looks very good!!
