You have right. An average resolution can be a good measure about a CBZ or CBR file.
When I first saw the Quality Check plugin I was very happy, because i though this was what I looking for.
But I found out, that I have mainly comic books in scanned format.
An addition and another addition to the Count Pages can give to the comics book collectors a big help. When a new scan appears, the DPI, and the pixels is the measure of its quality. (If you count the number of files too, you do the latest important measure, how many pages were scanned.)
