Originally I thought as you did and only went to 149 in the first block, and same goes for the width. But when I took the images into photoshop, I noticed that they were no longer each 218x150. They were all missing one pixel depending on which row they were in (eg 217x150 or 218x149).

Sounds like a bug in either Imager or its docs. {grin}
