The cropped portrait for the thumbnail is the 18th president.
They are in random order.
If you don't know what cropped means, it is a partial view of a picture but made partial, not automaticly partial.
I gave you 15 minutes because it may be hard for non-Americans and it also might be hard for Americans because the pictures are cropped!
Sorry if there's grammatical mistakes! If you do find them, let me know in the comments!
Newest Update: I am Renaming Presidents to what we usually call them, so we won't be confused :)
Notes for newest update: Actual first names are removed, but middle names are now initials, but the middle names most people know are still the full middle name
