Thanks, Here is what I am thinking and it works for me.
Built this concept app just for showing that I am doing.
Try it out.
Using @Jeff_Hager 's floor method of checking if a number is even or odd:
The LIKE Count is how many times the image has been clicked.
The FLOOR is a Math column described that returns a number.
Then the IF:Odd column checks if there is a match.
If it DOES NOT match the Like Counter is ODD, which means the image was clicked an ODD number of times. Which means the user wants to LIKE it (starting with 1)
If it DOES match, the Like Counter is EVEN, which means the image was clicked an EVEN number of times, Which means the user does not want to like it. (starting with 2, or not clicking at all)
