Usually, I take always 2-4 photos in a row instead of one - then try to pick the best one. But once the differences are very small, it's hard to tell which photo is better by simple looping using Irfan View.

Is there a better tool or a trick, to zoom multiple photos simultaneously and compare them by detail?

Detailed dream tool description:

I need to display variable amount of photos, ideally in some sort of split screen. I need to zoom them all together (they are always of the same resolution and contain very very similar images). I need to be able to move all the zoomed frames by same offset as well as move the zoomed image in single frame.
I need to be able to finally click on the selected photo and have the application delete/archive the others.

What does it mean to compare photos in this case:

As I have stated above, the photos I compare are taken sequentially. This means they contain almost the same images (+-some offset if my hands shake).
What I compare are details like blinking eyes, brightness, things in background and mostly the sharpness of the photo, which may not be obvious until the photo is zoomed.

I'm using FastStone Image Viewer for this, but I have tried XnView as well.

You can have up to four images and each fill almost a quarter of the screen. When you zoom in or out, all four images are zoomed by the same amount. When you zoom in so that the image is larger than its display area, you can click and drag on an image to pan it. As you pan, each photo is panned in unison, making it easy to compare the actual pixels in each image.
