From this code I thought that if I want to see if the signature is enabled i have to check the bit #1, #2 for avatar, #4 for images, #8 for coppa, and #16 for email.

Check Bit #4096 to see if the user want's to receive notifications about new PMs via eMail?
Maybe dozenzs of years in the future ... 65535 Bit-Systems ^.^

No. These are decimal values.

WHERE options & 16 checks if Bit #5 (2^4=16) is set.
