I'm now using this, and it works quite well. I added it to
greydragon's paginator, and the information is correct, and the
performance is quite reasonable.

However, I'm having trouble adapting the thumbnav to use this. When I
browse via dynamic/updates, my virtual album has over ten thousand
items, and in order to extract the [9] surrounding images, I currently
search through all items for the first one that matches
$item->rand_key. This is rather slow and often seems to be taking too
much memory; I'm getting PHP crashes in xdebug.so (I haven't debugged
this, but even with smaller albums, it's rather slow).

In the theme's paginator, I don't need to do this, since I have a
$position variable and I only need to extract
$theme->siblings()[$position-something] to [$position+something].

Is there an easier way for me to this from an arbitrary image block,
given just $item?

Thanks
