Great post Al!
I never open Word documents to view images (one or several). If, for some reason, multiple small images can’t be added to one image, or one would like to post one bigger than 640 x 480 (which most of the time is quite large), then a zip file is very useful. But in my opinion a posted small image is much better. Or, for those who have the possibility, posting a link to the image. But it isn’t ready to be seen in the thread and the link may stop working, as we all know.
The last 1-2 years I have made all my images, combined or not, in my posts with Microsoft Paint, which is there on all Windows versions.
