I just wanted to show you a sample of the ‘masonry’ layout in my ‘global gallery‘ plugin (see below).
The space between images can easily be adjusted to taste.
This layout used to be available in your ‘nexgen gallery’ plugin, but they eliminated it.
I can incorporate this plugin into your website if you like this layout better ( i actually prefer it ).
A license fee for the plugin is $35. I’ll give you a $35 discount on my time if you’d like.
Let me know what you think.
