Just installed Image Wall plugin on my blog.
Being new to WordPress, at first, I had some difficulties to make it work.
After a few emails to Gustav Andersson, the plugin is now working as expected. The author was very professional and willing to help. I didn't have to wait for days to get an answer to my questions.
Image Wall is to be added high on the list of "must have" plugins.
We are very lucky that this plugin be avaliable for free!
To those who use it, please give credit to the author! He deserves it. This guy is a genius.
