Oh, OK I think I’m starting to get it. Sorry if this seems trivial to you.
For some reason it’s been a grey area for me.
The one thing about this jQuery plugin is that it looks like the images need to be sized. Is there a Pinterest-like Dynamic layout grid that sizes the pics automatically? Or better yet–work with the Next Gen Gallery?
It depends what you want, really. By default, the plugin will leave the size of the images alone and just fit them as good as possible. But if you want the width of each picture to be the same (I believe that’s how Pinterest has it), then you should be able to do that by setting the width in CSS.
You’ll learn a lot from just trying things out, don’t be scared to experiment a little.
