It seems to depend on embedded thumbnail within the JPEG file. When it includes low-resolution thumbnail (ex. 160*120px), Geosetter just displays the low-resolution thumbnail, as you reported. But when the JEPG file includes no thumbnail image, Geosetter makes thumbnail image with "not bad" quality (using the Windows' function?).

So, a workaround is to remove low-res thumbnail from the file using some other tool (ex. exiftool), or use editing software that makes good quality thumbnail.

Anyway, it is not a Geosetter matter, I think.

My previous comment "it is not a Geosetter matter" is maybe wrong/inadequate.
The issue might be solved if Geosetter *always* use/read Windows' thumbnail, instead of embedded Exif thumbnail in JPEG file.

If GeoSetter "generates" a pseudo thumbnail if there is none, could it check the resolution and if it is too low, pretend there is no thumbnail and generate one of better quality (maybe with a parameter that says to do it)?
