This is a re-test (suggested by shalym above) of storing my embedded images as attachments (as I tried and abandoned long ago). For comparison purposes, this is my first post from this thread, with image URLs changed to point to the attachments.

This is the battery from a PW3 (identical to that in my dead PW2, whose battery is now in my PW3), with the outer label peeled off, and the metal "tray" removed. It was inflated (like most dead LiPo batteries). I tore the foil pouch opening it. I hope the gases I inhaled were not TOO toxic.

Here is a cropped closeup from that the photo above, showing circuit details.

Okay, now here is where I have a problem with this "image attachment" method. How do I get rid of that jumble of "too small to be useful" thumbnail images below the body of this post? I know how to (mostly) hide things with a SPOILER tag in the main body, but how can I do that outside the body, in the "Attached Thumbnails" block? This is the main reason I abandoned this obvious method early on, before I learned about the wiki (and later profile albums), both of which have their own drawbacks, but at least I can control them.
EDIT: Just a thought, but feedback would be appreciated: should I wrap images in a [SPOILER] tag (Show button), like in this post: https://www.mobileread.com/forums/sho...09#post2101509
