Unless I'm misreading Imager's docs, or it works in some bizarre ways, you're duplicating a thin line of pixels at each border. I think you want top 0, bottom 149 in one picture, and top 150, bottom 300 in the other. Similarly for left and right.

On a more general note, since you'll be now editing this portion of the code anyway {grin}, I'd get rid of that complex series of constants and use a computed loop anyway.
