How to Search Mulitple images of different resolution and return 1 match

i have images of different reoslution say image 1 of resolution 1 and image 2 of resolution 2

now when i run the test i want to search both images and return the one image that is found.
currently i am using os.dir and checking exists using for loop
is there an inbuilt method like findany() where i get first match from list of images
