Get the smallest resized highlight for the Album page

When the user clicks on an album, I'd like the album's highlight to be larger than the other thumbnails.

I've tried following

http://gallery.menalto.com/node/49864, and changed fetchThumbnailsByItemIds to fetchResizesByItemIds or fetchDerivativesByItemIds but it didn't work.

I also tried loading imageViews on the album page but I don't know enough code to work with $theme.imageViews[$theme.imageViewsIndex]

Can i get a tip pretty please?
