Ok, just saying, but this site seems a bit broken. The exact question I want to ask has been addressed, but I can't enter that conversation/thread because I don't have 50 reputation points. So ... I am allowed to create a duplicate and redundant question, but not provide useful information to an existing thread???
Relative to the earlier thread ... I've tried every solution proposed there and none of them have worked. Maybe since the last response in that thread someone has come across another approach? Note that SOME of my icons (all .jpg) have thumbnails.
