What you mean by "check if the pictures in these files are equal or different"?
Can you provide more details about files comparision? What kind of property(ies) you want to compare?

no image with no name which one is different which one you want to check it

Try just a simple binary compare of the content.

Here is a simple way that uses File.ReadAllBytes(), if you have large files however this is not the most efficient way: https://www.dotnetperls.com/file-equals[^]
