Q:

Photoset-grid + lighbox opens wrong image on click

I'm using Stylehatch's 'Photoset-grid.js' and 'view.js'
It seems to work, aside for this fact: When I click on the right-most image in a multi-image row, it opens the left image.
To see what I mean: http://test-theme-one.tumblr.com/
My rendered HTML looks like this (I went to safari and clicked "inspect element", and copied the html for a photoset post on my test blog) I don't understand how it is setup, I though I had it so an anchor would wrap each image in the photoset?
<div class="photoset-grid" data-layout="3" style="width: 100%;" data-width="500">

A:

The problem is that Photoset Grid wasn't really designed for template work.  It takes this template:
 {block:Photos}
      <a href="{PhotoURL-500}" class="view" rel="{PostID}">
            <img src="{PhotoURL-500}" alt="{PhotoAlt}"/>
      </a>
 {/block:Photos}

And pulls out all <img> tags and duplicates them--one per image in the row.  It results in this HTML:
<a class="view" ... >
    <div class="photoset-row cols-3" ...>
        <div class="photoset-cell" ...>
            <img ...>
        </div>
        <div class="photoset-cell" ...>
            <img ...>
        </div>
        <div class="photoset-cell" ...>
            <img ...>   
        </div>
    </div>
</a>
<a class="view" ... ></a>
<a class="view" ... ></a>

Now, view.js is using anchors/links to pop open the lightbox.  They are basically capturing the click event for the entire grouping.  When, in your template, you attempt to wrap the <img> in an <a>, it is pulling out the <img> tag out of the <a> in the template and appending them to the first <a>.
If you're up on jQuery plugin development, the Photoset-grid code, is pretty clearly bugged around line 113 (_setupColumns).
Long story short, you're not going to be able to use view.js lightbox with the Photoset-grid.  Unless some kind soul comes along and fixes the plugin.
