The idea is to be able to select an image file for analysis and receive a report of image quality. You could then do this for multiple copies of an image and then be able to select the best quality image, or trash any that are "deceptive" (large image dimensions, but relatively low image quality).

For example, if I have 2 images of the same subject (possibly cropped a little in one, but essentially the same image), one may be larger in dimensions than the other and with a larger file size, but the actual image quality could be different. One of many possible issues is someone having taken a copy of the original image file found somewhere on the internet and then resized it larger, then ran a sharpen filter on it, and saved with minimal image compression or even a lossless file type. But upon zooming into the image details you start to see artifacts that clearly show this was a manipulated image. Meanwhile, another file of the same image with smaller image dimensions, and possibly the same or slightly smaller file size, could reveal fewer artifacts when magnified... and thus be a better quality image.

Is there a Windows 10/11 app around (preferably free) that does this kind of analysis?
