Hi Sergey,

I tried the HASHFILE() approach, but, it also says the files are different even though I just "changed" one by simply saving it without actually making any edits to it.

BTW, I used a SHA256 in my testing.

>>r = filetostr(path to photo 1)

>>open photo 2 in a graphic editor (paint will do). Don't make any changes and save it.
>>s = filetostr(path to photo 2)
