Found the answer to my question…I was on the right track.

I’m guessing that d1.mbr, d1p1.img, and d1p2.img is the naming scheme used for a fixed-size/multiple partition, non-resizable image. So once I updated the image file config to that setting instead of single partition (realizable), it worked like a charm and imaged…

No can do, I really needed to get it going so I opted to redo my base Ubuntu install and start over. Everything’s working as expected now. Now the only thing I need to do is transfer over the rest of my images.
