The Poser render cache holds a separate .TMP file for each rendered image (see screenshot). I have set mine to keep the last 20 renders. They seem to be in some sort of "Poser-RAW" format.

For quick side-by-side render comparisons, I would like to be able to browse these images without having to use the Poser interface, and without having to export every render.

I guess I'm asking too much, hey?

I think MAC Preview will open them... never have tried, but I know it will open the Queue Cache Files.

Good thought, ratscloset, but I just tried and it won't.

The .tmp files are a custom tiled image formats that 3rd party applications can't read. Poser Pro will write cache files in the OpenEXR format for HDR and background renders, those will open in any application that reads OpenEXR.
