You can do it in the Finder, but not in Spotlight.MacOS can't do that? In Windows, you can open up a folder full of images, specify a type search and then use width and height to find images. If you display the folder as detailed items, you can go even further with the preset sort methods or add additional sorting column types.
Windows 7 and newer search is fairly powerful if you know how to use it. Puzzles me OSX/macOS doesn't have something as good if not better. For day to day searching, I use a third party indexer that indexes file names, whereas Windows does full-text indexing. I use it if I know what I want. I'll use Windows search if I remember a phrase or an entire sentence of text in a file and want to pull that file up but don't remember where I put it.
