OK. I applied this technique, along with WRITE PICTURE FILE. A single pass for all images took about 3 hours (about 1/3 the time it took before it would crash), and completely successful. I’m just waiting on finder to display the list of 151,814 image files. It does take awhile. 114.58Gb worth - previous versions of the extract using blobs ended up well over 1,2Tb.
So, to all, thank you. I needed a success - my wife of almost 39 years passed away from a long battle (10 years or more) with Vascular Dementia.
