the (very counterintuitiv) trick is to use BINFILE instead of FILE for local files in HTMLtext:
 "binfile:/full_filepath"

Been bitten by this lately, too.

Full path and BINFILE will work!

Unfortunately the html SIZE tags (height/width) of images will be ignored by Livecode, so the image will always be displayed in its original size.
You can however uncheck "fixed line height" to prevent more ugliness :-)
