@AqualRodinia Hi Mason,
You can try this commands below:-

import os
# it will print all files in that folder
print(os.listdir('folder path of the images'))

# it will print True of False if the file exists with this path
print(os.path.isfile('absolute path of the image'))

With my best wishes
Hope this helps
Please mark my answer if this helps.

maybe try: os.path.expanduser("Enter path here")
It can be used to import image.
