It worked as you suggested until I did a recent switch around to allow larger photos to be posted (I'm a visual guy... *vbg). Anyway, now, instead of going across row 1 and then across row 2, it jumps around to the middle of row 2, the end of row 2, then back to the beginning of row 2...

Maybe the first field fo row 2 is just slightly (1 pixel) lower than the rest of row 2 and the program considers it Row 3? I'll have to give that a whirl...
