That's a great suggestion for the current stock version of PhotoFloat. 
This wouldn't work well for the patched version 
(<http://git.jocke.no/photofloat/?h=patches>), that uses threading, and 
processes all the thumbnails for an image in parallell (then it would 
need to wait for the largest thumbnail to process, before beginning on 
the rest, compared to just do them all in parallell from the start).
