Images in a folder ( finding the largest height or width )

If I use <Width> or <Height> it only grabs it from the first image it finds in the folder if Im renaming folders.
Is there any way to have it find the largest <Width> or <Height> from any of the images in the folder ?
I want to use it to change the folder "Nature Images" to "Nature Images x50 2000x1000" using : "<Name> x<Num Files> <MaxWidth>x<MaxHeight>" fex

I don't think a lot of people know this, but you do. If you use file specific tags for a folder, the program will extract those tags from the first file in that folder. It will only analyze that single file. It will not seek through the list of files in that folder to finder a better value. The feature you need is too specific to your specific needs and I don't see how this could be implemented in an elegant way. Sorry.
