From a different thread, @gerryvz explained:
Thanks for explaining! What I experience (and you mention as in fact working-as-designed) is that #2 and #3 seem to do the exact same thing - i.e. insert a thumbnail sized image inline at the specified place. I must be missing something obvious though --- what should I expect as the difference between #2 and #3? Or should I not be expecting any difference? Are these cryptic forum controls a seemingly cruel but actually benevolent homage to the maddeningly obtuse control layout of the E500E HVAC system?
Are you sure his PC is Pentium-II class? I thought I saw a turbo button on his PC. I thought that only came on 80386 machines. (see, note pic below --- I am attaching as type="full" but what shows up is a thumbnail)

@Jlaa,
The forum's default set-up is to allow members to have three (actually four) options when it comes to attaching images:
1) attach an image and leave it in a group or image pool at the bottom of a post (along with other images if multiples are attached)
2) attach an image and insert it in-line at a specfied place, using the "Thumbnail" button at the time of attachment
3) attach an image and insert it in-line at a specified place, using the "Full Size" button at the time of attachment
4) link an image from an external source, or an internal image already posted to the forum, using the [ IMG] bbcode
In all images in scenarios one through three above, the image is automatically resized to a thumbnail at the time of import/attachment, It is stored in the forum's file system both as a thumbnail and a full-sized image, and displayed as a thumbnail in the actual post.

In scenario number four above, If an image is linked from an external source, it is automatically imported to this forum, proxied at that time, stored as both thumbnail and full-size image, and displayed as a thumbnail that can be clicked to be expanded.
GSXR's request to have the forum default to displaying thumbnails is the result of using Windows NT on his Intel Pentium and Pentium II-class microcomputers, with a 12-inch CRT display, and a USRobotics 56k V.92 dial-up modem. But I honored his request anyway, because he is a valued contributor and admin here.
