I recently started using WP (3.5.1) and was looking for a good photo gallery plugin. I found WPPA+ (4.9.18). It is relatively easy to use. I did spend some time trying to figure where to change certain settings. Fortunately, I was able to quickly leverage support forum - others have had same or similar questions in the past. WPPA+ has many features (you, as a user, can but do not have to get into) and the author's support is outstanding. I can recommend this plugin to anyone who needs a photo gallery on their site.
UPDATE (Jan 2016): I did my original review over two years ago after I started using WPPA+. I have been using it ever since. It is a great plugin. I just updated to the latest version. It has been very smooth and easy process. My rating now goes from 4 to 5 stars! Jacob, thanks for your continued great work. Dank u wel.
