AveIconBook Preview Size

Ok so I have many icons at 512x512px size and they display at that on AveIconBook.

I know I could just resize the preview pane, but my screen is relativly small so I'd like to keep it at a reasonable size.

What I was wondering is if I can force them to display at say 256x256, instead of having the larger icons being cropped, here's a shot of how it currently is at the moment.
