The pictures may be too large, max size is 2000k. You may just need to resize them some. IrfanView works great and is free. I've been using it for many years.

Autozone has a loaner tool that should work. Someone noted they used it for a lawn mower engine with a 2.5" (63.5mm) bore. Another used it on a BMW with a 91.97mm bore and states it can go smaller.
