1572,the year of FF8.

Considering that the resolution is so bad that Squall's hand isn't even visible and his entire left shoulder is missing, and that the boy actually does have quite lightly colored highlights in the right light, there is no reason at all to believe that that image depicts Zell.

IN FACT...

I have located a much better resolution shot.



Note the sleeves, which Zell is not wearing on his uniform. Also note the distinct lack of Zell's prominent headcrest, which would extend well above his head.

In short- NOT ZELL.
